*****************************************************************************

If you have ever used a redirecting service, you know that the redirect,
regardless of the typed in URL, always goes to the hardcoded URL, unless
you yourself handle the redirecting. Especially when the webredirect is done
in a frame.

*****************************************************************************

E.G.

http://www.myserver.com/testpage.html

using a redirect service goes to

http://realserver.myserver.com/

instead of 

http://realserver.myserver.com/testpage.html

*****************************************************************************

Any attempt to use JavaScript to fix this problem fails usually due to browser
security issues.

The correct method?

*****************************************************************************
include('redirect_uri.php3');
*****************************************************************************
All you have to do is prepend the above statement in your php code
or create a header file that contains the above statement and prepend it
to every page. (Make sure to put php markers around it - it won't work as HTML)

MAKE SURE THIS INCLUDE STATEMENT IS OUTSIDE OF ANY FUNCTIONS AND BEFORE ANY
HEADERS ARE OUTPUT PREFERABLY THE VERY FIRST LINE OF PHP CODE EXECUTED.

All your redirect worries will be fixed. The uri will now cascade to the
redirected url.
