If you want to direct traffic from your http so that it gets encrypted, this is really easy to do in Apache:
Step one: Set up your https vhost:
# other server options go here as needed
# - logging for example
# Add other SSL specific options as needed</pre>
Step two: Set up your http vhost:
RedirectPermanent / https://my.example.com/
We have previously posted more information on enabling SSL in Apache.
Obviously, instead of 10.1.1.1 and my.example.com you'll have to use your own IP and hostname, whatever they may be.
Note that this will redirect everything from http to https. Finer control is possible, for example you could do:
RedirectPermanent /secure/ https://my.example.com/secure/
Or you could use RewriteRules for even more control. However, in the age of mass surveillance and constant threats from hackers, a general redirect to https is a good idea.
