Getting response from external script by Apache mod

Lana has asked for the wisdom of the Perl Monks concerning the following question:

Hi :-)

Is there a way to send request to external perl script by adding some mod_rewrite condition and then, depending on script response, apply some rewrite rule?

I need something like this:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond IF SCRIPT /home/cgi-bin/ckw.cgi\?%{REQUEST_URI} RETURNS 1
RewriteRule ^.*$         (rewrite rule goes here) [L]
</IfModule>
[download]

Why do I need that? I have a MySQL database with keywords. When visitor clicks some link on my website, RewriteCond condition sends request to that ckw.cgi script with %{REQUEST_URI} as a query string. Script parses the request URI, search for keywords used in REQUEST_URI through database and returns 1 or 0. If it returns 1 - RewriteRule is applied for this link, elsif it returns 0 - no rules applied.

Is there a way to do this? My English is not perfect but I hope you understand me.

Thanks, Lana

You can use a rewrite map, and use an external program. Scroll down to External Rewriting Program, that should be exactly what you are looking for. But note that it is not handled as a CGI script, but uses its own, simple conventions.	[reply]

I know about RewriteMap but this not solves my problem as it doesnt allow to proceed to the next RewriteCond/RewriteRule through .htaccess file if there is no match in the database. Maybe there some other solution?	[reply]
