[support] API invoke during page refresh

[Kamal Palei]

Hi Jamie Holly
This was really a wondeful solution. I had to modify a bit as below. In
hook_init(), I added below code and was able to get the result as expected.

*    if(isset($_SERVER['REDIRECT_URL']))
    {
        if($_SERVER['REDIRECT_URL'] == '/mysite.com/system/ajax')
        {
            // Page requested via jQuery - AJAX. No need to reset
my session variables
        }
        else if($_SERVER['REDIRECT_URL'] == '/
mysite.com/my_custom_module/form/register')
        {
            // Non jQuery-AJAX page request. This is the place to reset
my session variables
        }
    }    *
**

 Thanks a lot.
