This might work with a RewriteRule [PT] flag.

I don't see how this (convoluted) configuration relates to this ticket though
(no "unix:" scheme involved), set to RESOLVED again.

I am not sure this is fixed for all cases.

I have recently run into an issue with the following config:


  RewriteEngine On
  RewriteCond "%{REQUEST_URI}" !^/___proxy_me/
  RewriteRule ^/(.*)$ "/___proxy_me/$1"
# [L,NE,B=%\ |:]

ProxyPass /___proxy_me/ "http://backend/; upgrade=websocket

What ends up happening is the backend server receives a url like:
%{document_root}%{request_uri}

>From logs of two apache servers main proxying to backend running in docker:

backend-1  | 172.21.0.2 - - [24/Mar/2024:10:49:02 +] "GET
/usr/local/apache2/htdocs/ HTTP/1.1" 404 196
main-1 | 172.21.0.1 - - [24/Mar/2024:10:49:02 +] "GET / HTTP/1.1" 404
196
backend-1  | 172.21.0.3 - - [24/Mar/2024:11:06:25 +] "GET
/usr/local/apache2/htdocs/test-url.html HTTP/1.1" 404 196
main-1 | 172.21.0.1 - - [24/Mar/2024:11:06:25 +] "GET /test-url.html
HTTP/1.1" 404 196

Fixed in trunk (r1893516) with Janne's patch which works better than mine when
the RewriteRule is in a directory/location context.

Attachment 38045 from bug 65590 is possibly more targeted since the "unix:"
scheme is a mod_proxy thing only.

Would that work for you?

Hey everyone. Is there anything I can do to speed up getting this included?
Since my last comment I've been running httpd with this patch without any
problems!

Hey Janne, I wanted to say thank you for your patch. It solves the problem for
me, too.

When will this be included in a release?

--- Comment #1 from Janne Peltonen  ---
Apparently, this is not a bug of mod_proxy but a bug of mod_rewrite.
mod_rewrite contains the function is_absolute_uri, and in case an uri is not
absolute, with the P flag, the uri will be passed on to the server itself as a
relative uri. The function has an explicit list of absolute uri prefixes it
recognizes, and "unix:" isn't contained in this list. This will lead to the
behaviour noticed by the original reporter. I'll add a patch that solved the
problem at least for me, by adding "unix:" as a recognized absolute uri scheme.
