Secure logins?

If you only want to have the actual login page handled by https., then you are lucky. In conf.php you can execute any PHP code. You can check the requested page if it contains /user and then set the base URL to contain https. You need to disable the login block or replace it by a link to the login page.

If you have troubles with a particular contrib project, please consider to file a support request. Thanks.

I created a patch which implements this. Test it, please: At the bottom of admin/user/configure you'll find a new checkbox. Check it and try -- of course, not on a real Drupal site, as you may find yourself locked out...

I played around with this quite a bit and got my .htaccess file to automatically redirect every page to https. So below is Drupal's .htaccess file. The only modification you need to make is to add two lines. Those lines are in the section: # Redirect to https version of site. Please note that some (still incomplete) testing suggests that the location of those two lines is important. Someone better at Apache rewrite rules could probably explain why. Anyway, this works great for my site. Also, note that this redirects to www version of a site all the time but that can be commented out easily per the comments in the file.

# Various rewrite rules.

RewriteEngine on

# Set "protossl" to "s" if we were accessed via https://. This is used later
# if you enable "www." stripping or enforcement, in order to ensure that

RewriteRule ^ - [E=protossl]
RewriteCond %{HTTPS} on
RewriteRule ^ - [E=protossl:s]

# Block access to "hidden" directories whose names begin with a period. This
# includes directories used by version control systems such as Subversion or
# Git to store control files. Files whose names begin with a period, as well
# as the control files used by CVS, are protected by the FilesMatch directive
# above.
#
# NOTE: This only works when mod_rewrite is loaded. Without mod_rewrite, it is
# not possible to block access to entire directories from .htaccess, because
# is not allowed here.
#
# If you do not have mod_rewrite installed, you should remove these
# directories from your webroot or otherwise protect them from being
# downloaded.
RewriteRule "(^|/)\." - [F]

# If your site can be accessed both with and without the 'www.' prefix, you
# can use one of the following settings to redirect users to your preferred
# URL, either WITH or WITHOUT the 'www.' prefix. Choose ONLY one option:
#
# To redirect all users to access the site WITH the 'www.' prefix,
# (http://example.com/... will be redirected to http://www.example.com/...)
# uncomment the following:
RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ http%{ENV:protossl}://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
#
# To redirect all users to access the site WITHOUT the 'www.' prefix,
# (http://www.example.com/... will be redirected to http://example.com/...)
# uncomment the following:
# RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
# RewriteRule ^ http%{ENV:protossl}://%1%{REQUEST_URI} [L,R=301]

# Modify the RewriteBase if you are using Drupal in a subdirectory or in a
# VirtualDocumentRoot and the rewrite rules are not working properly.
# For example if your site is at http://example.com/drupal uncomment and
# modify the following line:
# RewriteBase /drupal
#
# If your site is running in a VirtualDocumentRoot at http://example.com/,
# uncomment the following line:
# RewriteBase /
