You might do something like:
pageA.php
-------------------------------------
<?
if( user_realy_wants_page_b ) {
include( 'pageb.php' );
exit;
}
?>
Page A starts here...
-------------------------------------
That all happens on the server, and does not require anything outside of page A
to implement.

In the example above, any variables set in page A will be visible in page B when
it is included. The values must be set BEFORE the include() is hit.

<?
switch ( $Desired_Action ) {
case 'PageA' :
include( 'pagea.php' );
break;
case 'PageB' :
include( 'pageb.php' );
break;
case 'PageC' :
include( 'pagec.php' );
break;
default:
include( 'defailt.php' );
break;
}
would be one possibility.
