httpd has got a problem with encoded URLs
Last modified: 2012-05-14 04:15:58 EDT
Description of problem:
We use httpd (apache) as a reverse proxy for several underlying web servers. Now
especially in the case of a wiki, URLs may contain a percentage sign (%). This
is encoded as ASCII Hex ("%25"). But the reverse proxy sets it back to "%", so
there is no result but an error page.
Version-Release number of selected component (if applicable):
Everytime we try to use it.
Steps to Reproduce:
1. Configure httpd to act as a reverse proxy
2. Enter a URL including the encoded percentage sign (i.e. "%25")
The reverse proxy says "everything is okay" in the logfiles (even on maximum log
level), but asks the web server only for error page 400 (Bad request) and
The reverse proxy should forward the request "as it is" to the web server.
Selfmade apache (version 2.0.61) is working without this problem on RHEL3.
