svn commit: r1895981 - in /httpd/httpd/trunk/modules/proxy: mod_proxy.c mod_proxy.h proxy_util.c
Author: ylavic
Date: Wed Dec 15 11:35:36 2021
New Revision: 1895981
URL: http://svn.apache.org/viewvc?rev=1895981&view=rev
Log:
mod_proxy: follow up to r1895921: Don't prevent forwarding URIs w/ no hostname.
r1895921 changed proxy_detect() to disable forward proxying for URIs with no
hostname which is wrong, there might exist a third-party proxy module handling
the "urn:" scheme for instance (thanks Roy for the catch!).
For this to work, we also need to leave the forward proxied URI alone in
ap_proxy_pre_request() with no UDS special case or alike, a proxy module can
then catch (or not) the original URI as expected.
