[users@httpd] Infinite loop with RewriteRule

[Jan Eden <li...@janeden.org>]

Hi,

I have a problem with the following RewriteRule causing an infinite loop:

RewriteCond %{HTTP_HOST} (first|second|third|fourth)
RewriteRule ^(.+)$ %1/$1 [L,R,NC]

When requesting a URL like

http://firsthost/something

I end up getting something like

http://firsthost/first/first/first/first/first/first/first/first/first/something

and the server returns an error.

When changing the RewriteRule to this:

RewriteRule ^(.+)$ hardcoded/$1 [L,R,NC]

I get

http://firsthost/hardcoded/hardcoded/hardcoded/hardcoded/hardcoded/hardcoded/hardcoded/hardcoded/hardcoded/hardcoded/hardcoded/hardcoded/hardcoded/hardcoded/hardcoded/hardcoded/something

and the same error message

mod_rewrite: maximum number of internal redirects reached

Why is my pattern ^(.+)$ causing an infinite loop here?

This does not happen if the substitution string does not match the pattern itself, as in

RewriteCond %{HTTP_HOST} (first|second|third|fourth)
RewriteRule ^(something)$ %1/$1 [L,R,NC]

Thanks,

Jan
