I thin a .htaccess modification but i dont get it yet

Answer 1

This is my .htaccess content

BEGIN BM

RewriteEngine On RewriteBase /app/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d

this line redirects to show the url shorten eg: http :// mydomain.com/app/qwerty -> http :// somedomain.com

RewriteRule ^([0-9A-Za-z]+)/?$ /app/go.php?id=$1 [L]

what I want here is that when some user write http :// mydomain.com/ http:// otherdomain.com the redirection will be to http :// mydomain.com/?url=http :// otherdomain.com
