Redirect all site traffic from https://example.co.uk to https://www.example.co.uk

Hi Guys,

I've got an issue where I need to redirect all site traffic to the subdomain www. This is because the SSL certificate uses a SAN which is specifically http://www.example.co.uk. If a user goes to https://example.co.uk they get an SSL warning because the SAN doesn't match that URL. I can't change that unfortunately as that's what the customer has bought. I also have to redirect all traffic to HTTPS.

I have a redirect working for all HTTP traffic using the following in apache in the website conf file (using Mod Rewrite)

RewriteEngine On
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} ^example\.co.uk$ [NC]
RewriteRule (.*) https://www.example.co.uk%{REQUEST_URI} [R,L]

This works fine until a user goes to https://example.co.uk when it doesn't redirect.

I was wondering if I'd botched the rules somehow? If not, is what I'm trying to do possible before the user gets an SSL error or would I have to find some way of redirecting before the users hits the server and gets the SSL certificate? Can Linodes DNS tools do this somehow?

Ta!
