Apache 2.4 and mod_rewrite

Situation:  I have to serve up some webpages but I can't modify the content.  The content needs to be protected with a username and password and for that I'm using apache mod_digest over http (it's an internal site).

For tracking purposes outside of my control, I need to add the %REMOTE_USER name to the URI and then ignore it.

For example:

1. Browse to test.com

2. Get prompted for username and password (this is working fine)

3. Login successfully as user guest

4. Redirected to: http://test.com/guest/

5. All of the following calls get the same rules:  http://test.com/img1.jpg should be written as http://test.com/guest/img1.jpg

6. All of these user URIs should map to the same Location/DocumentRoot:

• http://test.com/guest/img1.jpg -> /var/htdocs/img1.jpg

• http://test.com/msalerno/img1.jpg -> /var/htdocs/img1.jpg

• http://test.com/msalerno -> /var/htdocs/

• http://test.com/guest -> /var/htdocs/

I'm still trying to get the configuration right. The only examples I can find do the inverse of what I need, they keep the URI the same but rewrite the directory location. I put the following rewrite rule in place, It does the most of what I need it to do, but at least it's a starting point.  It's still rewriting the internal directory.

RewriteEngine On
RewriteCond %{LA-U:REMOTE_USER} ^[a-z].*
RewriteCond %{REQUEST_URI} !/%{LA-U:REMOTE_USER}/(.+)$
RewriteRule ^(.*)$ /%{REMOTE_USER}/%1 [R]

Any help would be greatly appreciated.

Thanks

Re: Apache 2.4 and mod_rewrite

Unfortunately, the rules I pasted above cause too many redirects.  Still working on a solution.

Re: Apache 2.4 and mod_rewrite

Solution:

<Server>
AliasMatch "^/users/.*" "/usr/local/apache2/htdocs/"
..
<Directory "/usr/local/apache2/htdocs">
    AuthType Basic
    AuthName "Authentication Required"
    AuthUserFile "/usr/local/apache2/Basic_pw"

    Require valid-user

    RewriteEngine on
    RewriteCond %{REQUEST_URI} !/users/(.+)$
    RewriteRule ^(.*)$ /users/%{REMOTE_USER}/$1 [R]

...

I was making it way too complicated
