Force https for entire server/domain

Question

I am developing a number of forms which should only be accessed via https. I have a dedicated server with its own cert and all the good stuff.

So my question is two-fold really:

1). What's the best way to force every request to be https? Is there a better way than this .htacess/mod_rewrite rule:

RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

2). Are there any potential pitfalls or downside to forcing everything to be https that I should be thinking about (other than overhead, which wouldn't seem to be an issue anyway)?

Answer 1

What you have should be fine, this is what I use:

RewriteCond %{HTTPS} !=on
RewriteRule ^/(.*) https://%{SERVER_NAME}/$1 [R,L]

The R signifies it's a redirect instead of a rewrite, and the L indicates that the rewrite engine should not perform any more rewrites.

I originally found this here: Httpd Wiki

Edit:

I forgot to mention the SSLRequireSSL directive that forces all requests to be over HTTPS. Details can be found in the Apache Documentation.
