sorry,it not works.If you have any other suggestion please let me know.

thnx for your response.

1) Are you loading mod_rewrite in your httpd.con, or included .conf file e.g.

LoadModule rewrite_module          xxxxxxxxxxxx/mod_rewrite.so

2) Where are you adding the rules: in the apache  httpd.conf  or a .htaccess file?

a) If the httpd.cont, then the following in the appropriate Virtualhost definition should do:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^/rid/shop.php/([^/]*)/([^/]*)[/]*   /rid/shop.php?menu_id=$1&lang=$2  [L]

b) If a .htaccess  you must have  an "AllowOverride" line in you httpd.conf, to allow the use of .htaccess files, along with a suitable option to the command e.g. all

c) Which directories .htaccess are you placing the rules in?

If it's the root, then the following may work:

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^rid/shop.php/([^/]*)/([^/]*)[/]*   /rid/shop.php?menu_id=$1&lang=$2  [L]
