Tricky 301 Redirect Help

This may be a cinch for some, but after a couple hours of tinkering I still can't get it.

I want to 301 redirect

DOMAIN/FOLDER/mt-comments.cgi?__mode=red&id=ANY

to www.DOMAIN.com

The tricky part is that I only want to trigger the redirect if the url contains ?__mode=red - if I trigger the redirect for any query string following mt-comments.cgi I run into other unacceptable problems.

Thanks!

 

Try

RewriteEngine on
RewriteCond %{REQUEST_URI} ^/folder/mt-comments.cgi
RewriteCond %{QUERY_STRING} __mode=red
RewriteRule (.*) http://www.domain.com [R=301]

Thank you so much Johnt!! The redirect works under the right conditions and doesn't interfere with mt-comments.cgi functionality.

One last question: once the redirect happens, the URL looks like this:
www.DOMAIN.com/?__mode=red&id=ANY

Is there a way to strip off the ?__mode=red&id=ANY
Thanks!

 

If you want to get rid of the entire query string after a redirect you can use ? after the url you are redirecting to, i.e.

RewriteEngine on
RewriteCond %{REQUEST_URI} ^/folder/mt-comments.cgi
RewriteCond %{QUERY_STRING} __mode=red
RewriteRule (.*) http://www.domain.com/? [R=301]

Code (markup):

If you need to keep other aspects of the query string but just remove that one parameter / value pair, I'm not sure if you can do that. However, in this instance I think that the above is what you're after.

Perfect, thanks so much!

 

Will that work for individual pages pointed to different URL'S, or does it only work for one domain to another?

 

thanks so much
