htaccess redirect to base URL if URL contains parameter

问题

I need to redirect all url's that contain the parameter ?lang= to my base url.

For example: If www.example.com/?lang=ru redirect to www.example.com.

I have tried with RedirectMatch but it's not working.

Thanks!!!

回答1:

The Redirect* directives do not handle the query string so you need to use URL rewriting instead.

RewriteEngine on

# if the query string contains a parameter called "lang"
RewriteCond %{QUERY_STRING} (?:^|&)lang=
# then redirect (permanently) to /
RewriteRule ^ / [L,R=permanent]

Using Regular Expressions

If you want to use a Regular Expression to redirect something, use the RedirectMatchdirective:

RedirectMatch "^/lang=ru?.html/?$" "http://example.com/newfile.php"

Don't forget have mod_rewrite on in your apache configuration, and other configuration neccessary for enable your htaccess file.
