Removing GET parameter in .htaccess

Question

I\'m not able to remove one GET parameter wrongly added by one 404 SEF module.

I want to remove \"task=view\" only if it appears alone and not with another parameter

Answer 1

Use this rule:

RewriteCond %{QUERY_STRING}  ^task=view$ [NC]
RewriteRule ^(.*)$ $1? [R=301,L]

? at the end of $1 will strip-off any existing query string.
