SSLRequireSSL setting in Apache

The simplest way is usually the best and even takes the longest time in its search. Well recently I was building something, where I should limit the access only to https:// (as opposite of http:// where no SSL encryption occur).

Simply adding SSLRequireSSL directive to the definition of an access point in the Apache configuration makes it to require the use of SSL encryption.

Surely it should be added that redirection from regular http should be implemented.
