Redirect all traffic to index.php using mod_rewrite

I'm trying to build a url shortener, and I want to be able to take any characters immediately after the domain and have them passed as a variable url. So for example

• http://google.com/asdf

would become

• http://www.google.com/?url=asdf.

Here's what I have for mod_rewrite right now, but I keep getting a 400 Bad Request:

RewriteEngine on  
RewriteCond %{REQUEST_FILENAME} !-f  
RewriteCond %{REQUEST_FILENAME} !-d  
RewriteRule ^(.*) index.php?url=$1 [L,QSA]  

Solution 1:

Try replacing ^(.*) with ^(.*)$

RewriteRule ^(.*)$ index.php?url=$1 [L,QSA]

Edit: Try replacing index.php with /index.php

RewriteRule ^(.*)$ /index.php?url=$1 [L,QSA]

Solution 2:

ByTheWay don't forget to enable mod rewrite,in apache on ubuntu

sudo a2enmod rewrite 

and then restart apache2

sudo /etc/init.d/apache2 restart

edit: it is an old question that helped me but I lost hours testing my apache2.conf file on one side and .htaccess file on the other side and still no light.

Solution 3:

To rewrite all requests to /index.php ,you can use :

RewriteEngine on


RewriteCond %{REQUEST_URI} !^/index.php$
RewriteRule ^(.+)$ /index.php?url=$1 [NC,L]

The RewriteCondition RewriteCond %{REQUEST_URI} !^/index.php$ is important as it excludes the rewrite destination we are rewriting to and prevents infinite looping error.
