Rewrite proxypass

Hi,

I have a Apache 2.0 web server. When a users comes in to sitea.com a check is applied if the path ends with *t*, the user hits a rewrite rule that adds an environment variable called x is hit with a proxypass. This has worked successfully in the past, but recently I added another rewrite rule that states if file is not found in document root then look at this path on the file system. If the file is in another path then the document root, the user is prompted with a 404 error. If I remove the proxy pass from the first rewrite rule that adds a variable then everything works fine. Does anyone know why this occurs? I know I can fix this issue by removing [P] from the rewrite rule, but what is explanation to this problem?

Plack::Middleware::Auth::Basic(3pm)			User Contributed Perl Documentation		       Plack::Middleware::Auth::Basic(3pm)

NAME
Plack::Middleware::Auth::Basic - Simple basic authentication middleware SYNOPSIS
use Plack::Builder; my $app = sub { ... }; builder { enable "Auth::Basic", authenticator => &authen_cb; $app; }; sub authen_cb { my($username, $password) = @_; return $username eq 'admin' && $password eq 's3cr3t'; } DESCRIPTION
Plack::Middleware::Auth::Basic is a basic authentication handler for Plack. CONFIGURATION
authenticator A callback function that takes username and password supplied and returns whether the authentication succeeds. Required. Authenticator can also be an object that responds to "authenticate" method that takes username and password and returns boolean, so backends for Authen::Simple is perfect to use: use Authen::Simple::LDAP; enable "Auth::Basic", authenticator => Authen::Simple::LDAP->new(...); realm Realm name to display in the basic authentication dialog. Defaults to restricted area. LIMITATIONS
This middleware expects that the application has a full access to the headers sent by clients in PSGI environment. That is normally the case with standalone Perl PSGI web servers such as Starman or HTTP::Server::Simple::PSGI. However, in a web server configuration where you can't achieve this (i.e. using your application via Apache's mod_cgi), this middleware does not work since your application can't know the value of "Authorization:" header. If you use Apache as a web server and CGI to run your PSGI application, you can either a) compile Apache with "-DSECURITY_HOLE_PASS_AUTHORIZATION" option, or b) use mod_rewrite to pass the Authorization header to the application with the rewrite rule like following. RewriteEngine on RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L] AUTHOR
