How do I remove parameters with mod_rewrite

[friskybits]

Hi,

My home page URL has been indexed by Google in the form http://www.example.co.uk/?adCode=melon. I want to get rid of the /?adCode=melon bit and send a 301 redirect to Google so that my listing becomes http://www.example.co.uk.

I tried doing this with Redirect but it doesn't seem to work for form parameters. Some initial investigation leads me to believe that I need to use mod_rewrite with a RewriteCond of 'QUERY_STRING'. I've had a few goes at this but haven't managed to fix the problem.

Does anyone know how to write a RewriteRule to do this?

Thanks,

Thanks Jim,

this is what I have come up with. It seems to work but I'm not totally sure why.

RewriteEngine On
RewriteLog logs/rewrite.log
RewriteLogLevel 9
RewriteCond %{QUERY_STRING} ^(.*)adCode(.*)$
RewriteRule ^(.*)$ http://www.example.co.uk? [R=301,L]

Does it look OK to you?

Regards,

Martin

If you simply want to delete the entire query string and redirect to your main page (as your code above does), you can shorten that to:

RewriteEngine On
RewriteLog logs/rewrite.log
# RewriteLogLevel 9
RewriteCond %{QUERY_STRING} adCode
RewriteRule .* http://www.example.co.uk/? [R=301,L]

Do not leave that "LogLevel 9" in there on a live server -- This will significantly slow down your server. Comment it out as shown, or delete it entirely.

If you want to retain some of the query parameters or retain the requested page name, then the code will require modification.

Thanks Jim,

I knew that there would be a simplification but I didn't know what.

Many thanks for your help.
