+# Caddy Dynamic Configuration Management
+
+## Overview
+
+The HTTPS configuration system now automatically generates and manages the Caddy configuration in real-time. When an admin updates settings through the admin panel, the Caddyfile is regenerated and reloaded without requiring a full container restart.
+
+## How It Works
+
+### 1. **Configuration Generation**
+When admin saves HTTPS settings:
+1. Settings are saved to database (HTTPSConfig table)
+2. `CaddyConfigGenerator` creates a new Caddyfile based on settings
+3. Generated Caddyfile is written to disk
+
+### 2. **Configuration Reload**
+After Caddyfile is written:
+1. Caddy reload API is called via `docker-compose exec`
+2. Caddy validates and applies new configuration
+3. No downtime - live configuration update
+
+### 3. **Fallback Configuration**
+If HTTPS is disabled:
+1. System uses default hardcoded configuration
+2. Supports localhost, internal domain, and IP address
+3. Catch-all configuration for any other requests
+
+## Files Involved
+
+### New Files
+- **`app/utils/caddy_manager.py`** - CaddyConfigGenerator class with:
+  - `generate_caddyfile()` - Generates Caddyfile content
+  - `write_caddyfile()` - Writes to disk
+  - `reload_caddy()` - Reloads via Docker
+
+### Updated Files
+- **`app/blueprints/admin.py`** - HTTPS config route now:
+  - Generates new Caddyfile
+  - Writes to disk
+  - Reloads Caddy automatically
+  - Reports status to user
+
+## Admin Panel Workflow
+
+### Step 1: User Fills Form
+```
+Admin Panel → HTTPS Configuration
+- Hostname: digiserver
+- Domain: digiserver.sibiusb.harting.intra
+- Email: admin@example.com
+- IP: 10.76.152.164
+- Port: 443
+```
+
+### Step 2: Admin Saves Configuration
+- POST /admin/https-config/update
+- Settings validated and saved to database
+- Caddyfile generated dynamically
+- Caddy reloaded with new configuration
+
+### Step 3: User Sees Confirmation
+```
+✅ HTTPS configuration saved successfully!
+✅ Caddy configuration updated successfully!
+Server available at https://digiserver.sibiusb.harting.intra
+```
+
+### Step 4: Configuration Live
+- New domain/IP immediately active
+- No container restart needed
+- Caddy applying new routes in real-time
+
+## Generated Caddyfile Structure
+
+**When HTTPS Enabled:**
+```caddyfile
+{
+    email admin@example.com
+}
+
+(reverse_proxy_config) {
+    reverse_proxy digiserver-app:5000 { ... }
+    request_body { max_size 2GB }
+    header { ... }
+    log { ... }
+}
+
+http://localhost { import reverse_proxy_config }
+http://digiserver.sibiusb.harting.intra { import reverse_proxy_config }
+http://10.76.152.164 { import reverse_proxy_config }
+http://* { import reverse_proxy_config }
+```
+
+**When HTTPS Disabled:**
+```caddyfile
+{
+    email admin@localhost
+}
+
+(reverse_proxy_config) { ... }
+
+http://localhost { import reverse_proxy_config }
+http://digiserver.sibiusb.harting.intra { import reverse_proxy_config }
+http://10.76.152.164 { import reverse_proxy_config }
+http://* { import reverse_proxy_config }
+```
+
+## Key Features
+
+### ✅ No Restart Required
+- Caddyfile changes applied without restarting containers
+- Caddy reload API handles configuration hot-swap
+- Zero downtime configuration updates
+
+### ✅ Dynamic Configuration
+- Settings in admin panel → Generated Caddyfile
+- Database is source of truth
+- Easy to modify in admin UI
+
+### ✅ Automatic Fallbacks
+- Catch-all `http://*` handles any host
+- Always has localhost access
+- Always has IP address access
+
+### ✅ User Feedback
+- Admin sees status of Caddy reload
+- Error messages if Caddy reload fails
+- Logging of all changes
+
+### ✅ Safe Updates
+- Caddyfile validation before reload
+- Graceful error handling
+- Falls back to previous config if reload fails
+
+## Error Handling
+
+If Caddy reload fails:
+1. Database still has updated settings
+2. Old Caddyfile may still be in use
+3. User sees warning with status
+4. Admin can manually restart: `docker-compose restart caddy`
+
+## Admin Panel Status Messages
+
+### Success (✅)
+```
+✅ HTTPS configuration saved successfully!
+✅ Caddy configuration updated successfully!
+Server available at https://domain.local
+```
+
+### Partial Success (⚠️)
+```
+✅ HTTPS configuration saved successfully!
+⚠️ Caddyfile updated but reload failed. Please restart containers.
+Server available at https://domain.local
+```
+
+### Configuration Saved, Update Failed (⚠️)
+```
+⚠️ Configuration saved but Caddy update failed: [error details]
+```
+
+## Testing Configuration
+
+### Check Caddyfile Content
+```bash
+cat /srv/digiserver-v2/Caddyfile
+```
+
+### Manually Reload Caddy
+```bash
+docker-compose exec caddy caddy reload --config /etc/caddy/Caddyfile
+```
+
+### Check Caddy Status
+```bash
+docker-compose logs caddy --tail=20
+```
+
+### Test Access Points
+```bash
+# Test all configured domains/IPs
+curl http://localhost
+curl http://digiserver.sibiusb.harting.intra
+curl http://10.76.152.164
+```
+
+## Configuration Database
+
+Settings stored in `https_config` table:
+```
+https_enabled: boolean
+hostname: string
+domain: string
+ip_address: string
+email: string
+port: integer
+updated_at: datetime
+updated_by: string
+```
+
+When admin updates form → Database updated → Caddyfile regenerated → Caddy reloaded

+
+## Implementation Details
+
+### CaddyConfigGenerator Class
+
+**generate_caddyfile(config)**
+- Takes HTTPSConfig from database
+- Generates complete Caddyfile content
+- Uses shared reverse proxy configuration template
+- Returns full Caddyfile as string
+
+**write_caddyfile(content, path)**
+- Writes generated content to disk
+- Path defaults to /srv/digiserver-v2/Caddyfile
+- Returns True on success, False on error
+
+**reload_caddy()**
+- Runs: `docker-compose exec -T caddy caddy reload`
+- Validates config and applies live
+- Returns True on success, False on error
+
+## Advantages Over Manual Configuration
+
+| Manual | Dynamic |
+|--------|---------|
+| Edit Caddyfile manually | Change via admin panel |
+| Restart container | No restart needed |
+| Risk of syntax errors | Validated generation |
+| No audit trail | Logged with username |
+| Each change is manual | One-time setup |
+
+## Future Enhancements
+
+Potential improvements:
+- Configuration history/backup
+- Rollback to previous config
+- Health check after reload
+- Automatic backup before update
+- Configuration templates
+- Multi-domain support
+
+## Support
+
+For issues:
+1. Check admin panel messages for Caddy reload status
+2. Review logs: `docker-compose logs caddy`
+3. Check Caddyfile: `cat /srv/digiserver-v2/Caddyfile`
+4. Manual reload: `docker-compose exec caddy caddy reload --config /etc/caddy/Caddyfile`
+5. Full restart: `docker-compose restart caddy`

+# HTTPS Configuration Management System
+
+## Overview
+
+The DigiServer v2 now includes a built-in HTTPS configuration management system accessible through the Admin Panel. This allows administrators to enable and manage HTTPS/SSL settings directly from the web interface without needing to manually edit configuration files.
+
+## Features
+
+- **Enable/Disable HTTPS**: Toggle HTTPS on and off from the admin panel
+- **Domain Management**: Set the full domain name (e.g., `digiserver.sibiusb.harting.intra`)
+- **Hostname Configuration**: Configure server hostname (e.g., `digiserver`)
+- **IP Address Management**: Set the IP address for direct access (e.g., `10.76.152.164`)
+- **Port Configuration**: Customize HTTPS port (default: 443)
+- **Status Tracking**: View current HTTPS status and configuration details
+- **Real-time Preview**: See access points as you configure settings
+
+## Workflow
+
+### Step 1: Initial Setup (HTTP Only)
+1. Start the application normally: `docker-compose up -d`
+2. The app runs on HTTP port 80
+3. Access via: `http://<server-ip>`
+
+### Step 2: Enable HTTPS via Admin Panel
+1. Log in to the admin panel as an administrator
+2. Navigate to: **Admin Panel → 🔒 HTTPS Configuration**
+3. Toggle the "Enable HTTPS" switch
+4. Fill in the required fields:
+   - **Hostname**: Short name for your server (e.g., `digiserver`)
+   - **Full Domain Name**: Complete domain (e.g., `digiserver.sibiusb.harting.intra`)
+   - **IP Address**: Server IP address (e.g., `10.76.152.164`)
+   - **HTTPS Port**: Port number (default: 443)
+
+### Step 3: Verify Configuration
+1. The status section shows your HTTPS configuration
+2. Access points are displayed:
+   - HTTPS: `https://digiserver.sibiusb.harting.intra`
+   - HTTP fallback: `http://10.76.152.164`
+
+## Configuration Details
+
+### Database Model (HTTPSConfig)
+
+The configuration is stored in the `https_config` table with the following fields:
+
+```python
+- id: Primary key
+- https_enabled: Boolean flag for HTTPS status
+- hostname: Server hostname
+- domain: Full domain name
+- ip_address: IPv4 or IPv6 address
+- port: HTTPS port (default: 443)
+- created_at: Creation timestamp
+- updated_at: Last modification timestamp
+- updated_by: Username of admin who made the change
+```
+
+### Admin Routes
+
+- **GET /admin/https-config**: View HTTPS configuration page
+- **POST /admin/https-config/update**: Update HTTPS settings
+- **GET /admin/https-config/status**: Get current status as JSON
+
+## Integration with Docker & Caddy
+
+The HTTPS configuration works in conjunction with:
+
+1. **Caddy Reverse Proxy**: Automatically handles SSL/TLS
+2. **Let's Encrypt**: Provides free SSL certificates
+3. **docker-compose.yml**: Uses the configured domain for Caddy
+
+### Current Setup
+
+**docker-compose.yml** uses `digiserver.sibiusb.harting.intra` as the primary domain.
+
+**Caddyfile** configurations:
+- HTTPS: `digiserver.sibiusb.harting.intra` (auto-managed SSL)
+- HTTP Fallback: `10.76.152.164` (direct IP access)
+
+## Prerequisites
+
+Before enabling HTTPS, ensure:
+
+1. **DNS Resolution**: Domain must resolve to the server's IP
+   ```bash
+   # Test DNS resolution
+   nslookup digiserver.sibiusb.harting.intra
+   ```
+
+2. **Ports Accessible**:
+   - Port 80 (HTTP): For Let's Encrypt challenges
+   - Port 443 (HTTPS): For secure traffic
+   - Port 443/UDP: For HTTP/3 support
+
+3. **Firewall Rules**: Ensure inbound traffic is allowed on ports 80 and 443
+
+4. **Hosts File** (if DNS not available):
+   ```
+   10.76.152.164 digiserver.sibiusb.harting.intra
+   ```
+
+## Database Migration
+
+To set up the HTTPS configuration table, run:
+
+```bash
+# From inside the Docker container
+python /app/migrations/add_https_config_table.py
+
+# Or from the host machine
+docker-compose exec digiserver-app python /app/migrations/add_https_config_table.py
+```
+
+## Access Points After Configuration
+
+### HTTPS (Recommended)
+- URL: `https://digiserver.sibiusb.harting.intra`
+- Protocol: HTTPS with SSL/TLS
+- Automatic redirects from HTTP
+- Let's Encrypt certificate (auto-renewed)
+
+### HTTP Fallback
+- URL: `http://10.76.152.164`
+- Protocol: Plain HTTP (no encryption)
+- Used when domain is not accessible
+- Automatically redirects to HTTPS
+
+## Security Features
+
+✅ Automatic SSL certificate management (Let's Encrypt)
+✅ Automatic certificate renewal
+✅ Security headers (HSTS, X-Frame-Options, etc.)
+✅ HTTP/2 and HTTP/3 support
+✅ Admin-only access to configuration
+
+## Logging
+
+All HTTPS configuration changes are logged in the server logs:
+
+```
+✓ HTTPS enabled by admin: domain=digiserver.sibiusb.harting.intra, hostname=digiserver, ip=10.76.152.164
+✓ HTTPS disabled by admin
+```
+
+Check admin panel → Logs for detailed audit trail.
+
+## Troubleshooting
+
+### HTTPS Not Working
+1. Verify DNS resolution: `nslookup digiserver.sibiusb.harting.intra`
+2. Check Caddy logs: `docker-compose logs caddy`
+3. Ensure ports 80 and 443 are open
+4. Check firewall rules
+
+### Certificate Issues
+1. Check Caddy container logs
+2. Verify domain is accessible from internet
+3. Ensure Let's Encrypt can validate domain
+4. Check email configuration for certificate notifications
+
+### Configuration Not Applied
+1. Verify database migration ran: `python migrations/add_https_config_table.py`
+2. Restart containers: `docker-compose restart`
+3. Check admin panel for error messages
+4. Review server logs
+
+## Example Configuration
+
+For a typical setup:
+
+```
+Hostname: digiserver
+Domain: digiserver.sibiusb.harting.intra
+IP Address: 10.76.152.164
+Port: 443
+HTTPS Status: Enabled ✅
+```
+
+Access via:
+- `https://digiserver.sibiusb.harting.intra` ← Primary
+- `http://10.76.152.164` ← Fallback
+
+## Future Enhancements
+
+Potential improvements for future versions:
+
+- Certificate upload/management interface
+- Domain validation checker
+- Automatic DNS verification
+- Custom SSL certificate support
+- Certificate expiration notifications
+- A/B testing for domain migration

+# HTTPS Email Configuration - Update Guide
+
+## What's New
+
+The HTTPS configuration system now includes an **Email Address** field that is essential for:
+- SSL certificate management (Let's Encrypt)
+- Certificate expiration notifications
+- Certificate renewal reminders
+
+## Changes Made
+
+### 1. **Database Model** (`app/models/https_config.py`)
+- Added `email` field to HTTPSConfig model
+- Updated `create_or_update()` method to accept email parameter
+- Updated `to_dict()` method to include email in output
+
+### 2. **Admin Routes** (`app/blueprints/admin.py`)
+- Added email form field handling
+- Added email validation (checks for '@' symbol)
+- Updated configuration save to store email
+- Updated logging to include email in configuration changes
+
+### 3. **Admin Template** (`app/templates/admin/https_config.html`)
+- Added email input field in configuration form
+- Added email display in status section
+- Added help text explaining email purpose
+- Email marked as required when HTTPS is enabled
+
+### 4. **CLI Utility** (`https_manager.py`)
+- Updated enable command to accept email parameter
+- Updated help text to show email requirement
+- Example: `python https_manager.py enable digiserver domain.local admin@example.com 10.76.152.164`
+
+### 5. **Database Migration** (`migrations/add_email_to_https_config.py`)
+- New migration script to add email column to existing database
+
+## Update Instructions
+
+### Step 1: Run Database Migration
+```bash
+# Add email column to existing https_config table
+python /app/migrations/add_email_to_https_config.py
+```
+
+### Step 2: Restart Application
+```bash
+docker-compose restart
+```
+
+### Step 3: Configure Email via Admin Panel
+1. Navigate to: **Admin Panel → 🔒 HTTPS Configuration**
+2. Fill in the new **Email Address** field
+3. Example: `admin@example.com`
+4. Click **Save HTTPS Configuration**
+
+## Configuration Form - New Field
+
+```html
+<!-- Email Field -->
+<label for="email">Email Address *</label>
+<input type="email" id="email" name="email" 
+       value="admin@example.com"
+       placeholder="e.g., admin@example.com"
+       required>
+<p>Email address for SSL certificate notifications and Let's Encrypt communications</p>
+```
+
+## CLI Usage - New Syntax
+
+**Old (still works for HTTP):**
+```bash
+python https_manager.py enable digiserver domain.local 10.76.152.164 443
+```
+
+**New (with email - recommended):**
+```bash
+python https_manager.py enable digiserver domain.local admin@example.com 10.76.152.164 443
+```
+
+## Status Display - Updated
+
+The status card now shows:
+```
+✅ HTTPS ENABLED
+Domain: digiserver.sibiusb.harting.intra
+Hostname: digiserver
+Email: admin@example.com  ← NEW
+IP Address: 10.76.152.164
+Port: 443
+Access URL: https://digiserver.sibiusb.harting.intra
+Last Updated: 2026-01-14 15:30:45 by admin
+```
+
+## Validation
+
+The system now validates:
+- ✅ Email format (must contain '@')
+- ✅ Email is required when HTTPS is enabled
+- ✅ Email is stored in database
+- ✅ Email is logged when configuration changes
+
+## Benefits
+
+📧 **Proper SSL Certificate Management**
+- Let's Encrypt sends notifications to configured email
+- Certificate expiration warnings before renewal
+
+📋 **Better Configuration**
+- Email is persisted in database
+- No need to set environment variables
+- Fully managed through admin panel
+
+🔐 **Professional Setup**
+- Real email address for certificate notifications
+- Easier to manage multiple servers
+- Complete audit trail with email address
+
+## Backwards Compatibility
+
+If you have an existing HTTPS configuration without an email:
+1. The email field will be NULL
+2. You'll see an error when trying to use HTTPS without email
+3. Simply add the email through the admin panel and save
+4. Configuration will be complete
+
+## Database Schema Update
+
+```sql
+ALTER TABLE https_config ADD COLUMN email VARCHAR(255);
+```
+
+New schema:
+```
+https_config table:
+├── id (PK)
+├── https_enabled (BOOLEAN)
+├── hostname (VARCHAR)
+├── domain (VARCHAR)
+├── ip_address (VARCHAR)
+├── email (VARCHAR) ← NEW
+├── port (INTEGER)
+├── created_at (DATETIME)
+├── updated_at (DATETIME)
+└── updated_by (VARCHAR)
+```
+
+## Example Configuration
+
+**Complete HTTPS Setup:**
+```
+Hostname: digiserver
+Domain: digiserver.sibiusb.harting.intra
+Email: admin@example.com
+IP: 10.76.152.164
+Port: 443
+Status: ✅ ENABLED
+```
+
+## Troubleshooting
+
+### Email Field Not Showing?
+1. Clear browser cache (Ctrl+Shift+Del)
+2. Reload the page
+3. Check that containers restarted: `docker-compose restart`
+
+### Migration Error?
+If migration fails:
+```bash
+# Option 1: Add column manually
+docker-compose exec digiserver-app python -c "
+from app.app import create_app
+from app.extensions import db
+from sqlalchemy import text
+app = create_app()
+with app.app_context():
+    db.engine.execute(text('ALTER TABLE https_config ADD COLUMN email VARCHAR(255)'))
+"
+
+# Option 2: Reset database (if testing)
+rm instance/digiserver.db
+python /app/migrations/add_https_config_table.py
+```
+
+### "Email Required" Error When HTTPS Enabled?
+- Admin panel: Fill in the Email Address field before saving
+- CLI: Include email in command: `python https_manager.py enable ... email@example.com ...`
+
+## Next Steps
+
+1. Run the database migration
+2. Restart the application
+3. Navigate to HTTPS Configuration
+4. Enter a valid email address (e.g., `admin@example.com`)
+5. Enable HTTPS
+6. System will use this email for Let's Encrypt notifications
