[users@httpd] modifying header in request
Hi!
I am currently trying to add the REMOTE_USER environment variable into a response header or forward header (using mod_jk).
However we also need to strip the first few characters of the REMOTE_USER when adding it to the header.
We are adding the header to the request response using mod_headers, however in apache 2.0 mod_headers does not support modifying a header using the "edit" action with regexps.
We have noticed the "edit" action for mod_headers directives only exist in apache 2.2.
Is there any way of doing this modification of REMOTE_USER when adding it to a header without upgrading to Apache 2.2? We can not do so due to other module dependencies.
Regards,
Cenk

Thanks for the advice Eric!
I looked it up and found information and examples like the one below. However the X_REMOTE_USER header always comes out empty, I can not figure out why. I can see that REMOTE_USER indeed contains an authentic username. According to mod_rewrite documentation the below directives should work out. Think I have seen other examples where it does not work either.
Is the code looking right? Is there a reason it should not work out on Apache httpd 2.0 on the win32 platform?
RewriteCond %{LA-U:REMOTE_USER} (.+)
RewriteRule ^(.*) - [L,P,E=RU:%1]
RequestHeader add X_REMOTE_USER %{RU}e

Can you use a rewritecond to capture what you want, drop it in a new
envvar [E=FOO:BAR], then use mod_headers to set the response header
from your the new envvar?
