i have two pages: A and B (.php) in A i have <IFRAME SRC="mov/b.php" > </IFRAME> in B i have some functions. facts: is a necessity to have that iframe problem: i need to block direct acces(visitors) to mov/b.php but in the same time i need the page B to work for me. I need that page to work only when in used in page A (in the iframe) and to have it block for other use. How do i do that? Can somebody help? I can't figure it out by myself. Thank you!
