Greetings,
Sorry for the "double" posting, let me just try to simplify the
exposition of the problem. I'm trying to rewrite a URI using regular
expression placeholders, but I'm having a problem that when a
placeholder doesn't match anything it still gets replaced in the
destination with a '1'. This is the configuration directive (basically
if the URI is rss2, rewrite to RSS2; but if it is rss only, rewrite to
RSS):
reqrep ^([^\ ]*)\ /rss(2*)(.*) \1\ /Endpoint/RSS\2\3
Calling rss2 correctly rewrites the URI:
=> /rss2?u=username correctly rewrites to /Endpoint/RSS2?u=username
However calling rss (without the '2') triggers a wrong replacement:
=> /rss?u=username incorrectly rewrites to /Endpoint/RSS1?u=username,
instead of /Endpoint/RSS?u=username
This is the content of the log:
10.134.15.124 - - [21/Aug/2009:12:08:33 +0100] "GET /Endpoint/RSS2?
u=username HTTP/1.1" 404 209
10.134.15.124 - - [21/Aug/2009:12:09:05 +0100] "GET /Endpoint/RSS1?
u=username HTTP/1.1" 404 209
Many thanks again.
Pedro.

Greetings,
I'm using a reqrep to search in a URI for either the "rss" or "rss2"
strings. The objective is to have the following mapping:
/rss?u=username => /Endpoint/RSS?u=username
/rss2?u=username => /Endpoint/RSS2?u=username
This is the reqrep I'm using:
reqrep ^([^\ ]*)\ /rss(2*)(.*) \1\ /Endpoint/RSS\2\3
This is the result:
10.134.15.124 - - [21/Aug/2009:12:08:33 +0100] "GET /Endpoint/RSS2?
u=username HTTP/1.1" 404 209
10.134.15.124 - - [21/Aug/2009:12:09:05 +0100] "GET /Endpoint/RSS1?
u=username HTTP/1.1" 404 209
When \2 exists, it is replaced accordingly, but when it doesn't a 1
is used for replacement, instead of an empty string... Any ideas of
what could be happening?
(Note that each return a 404, because there's not really any content
- this was just to test the regexp replacement.)
Thanks so much.
Pedro.
