Subject: Merge r527969 from trunk:
X-Git-Tag: 2.2.5~269
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=545f73efebf26aeb7e363619be06ddf27d395186;p=thirdparty%2Fapache%2Fhttpd.git

Merge r527969 from trunk:

HTTP proxy ProxyErrorOverride: Leave 1xx and 3xx responses alone.  Only
processing of error responses (4xx, 5xx) will be altered.

PR: 39245

This is based on a patch submitted by Bart van der Schans <schans hippo.nl>
and tweaked slightly by me based on discussions on dev@ since April 2006.
I think rpleum was the first to mention the 1xx issue.
