Retrieving the url anchor in a werkzeug request

Question

I have a DAV protocol that stores out-of-band data in the url anchor, e.g. the ghi in DELETE /abc.def#ghi. The server is a Flask application.

Answer 1

From Wikipedia (Fragment Identifier) (don't have the time to find it in the RFC):

The fragment identifier functions differently than the rest of the URI: namely, its processing is exclusively client-side with no participation from the server

So Flask - or any other framework - doesn't have access to #ghi.
