Removing Parameters from a URL

Question

I want to remove the parameter after the true url and then redirect to the same URL without this parameter

example:

I want to remove the "r" parameter from

http://www.mysite.com/123.html?r=1

and redirect to

http://www.mysite.com/123.html

using htaccess and 301 redirect

Thank you

Answer 1

Try the following:

RewriteRule ^123.html.? 123.html? [L]

Note that the second URL ends with ?, this removes the query string.
