how can i mod_rewrite this ?

Question

mydomain.com/dir/cgi-bin/mirror.cgi/http/www.test.com/

into

mydomain.com/www.test.com

Answer 1

Try this rule in your .htaccess file:

RewriteRule ^www\.[^/]+$ /dir/cgi-bin/mirror.cgi/http/$0/

That will rewrite a request of /www.example.com internally to /dir/cgi-bin/mirror.cgi/http/www.example.com/.

Answer 2

In the .htaccess file:

ModRewrite On
RewriteRule (([a-zA-Z0-9]([a-zA-Z0-9\-]{0,61}[a-zA-Z0-9])?\.)+[a-zA-Z]{2,6}) /dir/cgi-bin/mirror.cgi/http/$1/

Regex pulled from regexlib.com.

The first half defines a regular expression that matches valid domain names, and the second part is what it is redirected to (with $1 replaced by the matching domain).
