i want to remove a parameter after the true url then redirection to the same url without this parameter
example :
i want to remove the parameter "r" from
http://www.mysite.com/123.html?r=1
and redirection to
http://www.mysite.com/123.html
using htaccess and 301 redirect
thank you

Try this:
RewriteRule ^123.html.? 123.html? [L]
Note how the second url ends with a ?, this removes the query string.

Better than using a final ?, you should use the qsdiscard flag QSD, and the permanent redirect flag R=301. So for your example :
RewriteRule ^123\.html(.*)$ 123.html [QSD,L,R=301]
