SetEnvIf and mod_rewrite

["Kogelheide, Ryan SSBC:EX" <Ryan.Kogelheide@xxxxxxxxx>]

Hi everyone,

I need your help. I've been trying to check a header variable provided by top-level filter and proxy depending on it:

 

  SetEnvIf SERVERSESSIONID ".+" AUTHENTICATED

 

  RewriteCond %{ENV:AUTHENTICATED} 1

  RewriteRule ^/(.*) https://backend:7792/authenticated/$1 [P,L]

  ProxyPassReverse / https:// backend:7792/authenticated/

 

  RewriteCond %{ENV:AUTHENTICATED} !1

  RewriteRule ^/(.*) https:// backend:7792/unauthenticated/$1 [P,L]

  ProxyPassReverse / https:// backend:7792/unauthenticated/

 

But it's like mod_rewrite can't see the variable (in the rewrite log):

 

applying pattern '^/(.*)' to uri '/'

RewriteCond: input='' pattern='1' => not-matched

applying pattern '^/(.*)' to uri '/'

RewriteCond: input='' pattern='!1' => matched

 

I saw one post

 

http://turboflash.wordpress.com/2010/05/27/apache-environment-variables-visibility-with-setenv-setenvif-and-rewriterule-directives/

 

that said that sometimes variables aren't visible, but I don't really understand why. I think I'm missing something fundamental about how the httpd works.

 

I'm using Apache 2.0.64 and the directives are in a virtual host.

 

Cheers,

 

Ryan
