Hi All, Thanks for your replies. Actually i am placing this regex in .htaccess file. Here i have to redirect all the request to https if it is not for ogg file. The complete code is: RewriteCond %{HTTPS} off RewriteCond %{REQUEST_URI} ^.+\.ogg$ //Need some tweaking here. I know this code works just opposite. Need your help here. RewriteRule .* https://%{HTTP_HOST}/ [L] Hope this helps to understand the problem.
