apache redirect from non www to www

Question

I have a website that doesn\'t seem to redirect from non-www to www.

My Apache configuration is as follows:

RewriteEngine On
### re-direct t         


        

Answer 1

Using the rewrite engine is a pretty heavyweight way to solve this problem. Here is a simpler solution:

    ServerName example.com
    Redirect permanent / http://www.example.com/



    ServerName www.example.com
    # real server configuration

And then you'll have another section with ServerName www.example.com for your real server configuration. Apache automatically preserves anything after the / when using the Redirect directive, which is a common misconception about why this method won't work (when in fact it does).
