Force SSL / https:// using .htaccess for a Content Management System (CMS)

Content Management Systems often force pages to go though an index.php route.

For example pages on the CMS I use are presented in the URL as follows.

[To see links please register here]

The .htaccess code I know only listens to the index.php part of my statement.

My current re-write code stands as follows;

RewriteEngine On
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^login/?$

[To see links please register here]

[R=301,L]

This works as it is a specific directory, however,

RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^index.php?page=263$

[To see links please register here]

[R=301,L]

does not seem to work.

Any ideas?

I have a snippet I copied from a webpage somewhere. Perhaps you could give it a try?

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

1. RewriteRule just matches the `path` section of the url, so it needs to be just `^index\.php$`.
2. The query string can be matched using `RewriteCond %{QUERY_STRING}`.
3. Like in aesphere's answer, testing for the special `%{HTTPS}` variable is easier than checking the port.
4. Using an absolute target URI implies `[R=301,L]` so you can remove it.
5. [QSA] appends the query string

So, you end up with:

RewriteCond %{HTTPS} off
RewriteCond %{QUERY_STRING} ^\?page=263$
RewriteRule ^index\.php$ https://%{HTTP_HOST}%{REQUEST_URI} [QSA]
