ScriptNameFix WSGI middleware.
|
|
|
|
When nginx strips the path prefix before forwarding to a Flask app it also
|
|
sets the X-Script-Name header (e.g. /digiserver). This middleware reads
|
|
that header and sets SCRIPT_NAME in the WSGI environ so that Flask's
|
|
url_for() generates absolute URLs with the correct prefix.
|
|
|
|
Usage in the app factory:
|
|
from app.utils.script_name_fix import ScriptNameFix
|
|
app.wsgi_app = ScriptNameFix(app.wsgi_app)
|
|
