.htaccess: Transparently adding a name to the request

Question

I've read this tutorial about how to modify your .htaccess in order to server many web2py applications but it doesn't seem to work. Here is my .htaccess

RewriteEngine On

RewriteRule ^dispatch\.fcgi/ - [L]
RewriteRule ^(.*)$ dispatch.fcgi/$1 [L]

RewriteCond %{HTTP_HOST} =www.moublemouble.com [NC, OR]
RewriteCond %{HTTP_HOST} =moublemouble.com [NC]
RewriteRule ^/(.*) /moublemouble/$1 [PT,L]

All I get is a 500 Internal Error and .htaccess is not my strong point. Any clues?

Answer 1

It might be your RewriteCond causing the problem.

I haven't tried it, but you could try...

RewriteCond %{HTTP_HOST} ^www.moublemouble.com [NC, OR]
RewriteCond %{HTTP_HOST} ^moublemouble.com [NC]
RewriteRule ^/(.*) /moublemouble/$1 [L]

Answer 2

It’s either the illegal space in [NC, OR] or you are getting a recursion loop since the substitution /moublemouble/… is also matched by the pattern ^/(.*). So try this:

RewriteCond %{HTTP_HOST} =www.moublemouble.com [NC,OR]
RewriteCond %{HTTP_HOST} =moublemouble.com [NC]
RewriteCond $1 !^moublemouble/
RewriteRule ^/(.*) /moublemouble/$1 [PT,L]

Or more compact:

RewriteCond %{HTTP_HOST} ^(www\.)?moublemouble\.com$ [NC]
RewriteRule !^/moublemouble/ /moublemouble%{REQUEST_URI} [PT,L]
