Description:
Returns the current URL for the page. Works better than other methods. Other methods of calculating the URL from CGI variables won't work if your application is in a sub-folder like http://localhost/myapp/ - they ignore the "myapp" bit. I've seen and tired all sorts of other ways to get the Current URL but this is the only method I have found that works in all secenarios.

Return Values:
Returns a string.

Example:

Parameters:

No arguments.
