Calling a secondary page (htm) manually in the browser

Hi all,

if a page1.htm calls page2.htm to process something. I noticed that if page2.htm is called manually by typing on the browser, page2.htm is loaded.

is there anything in BSP to controll that? I mean I don't want to load page2.htm unless is coming from page1.htm since there are certain paramaters that are been sent to

or this control has to be done manually on html and nothing to do with BSP?

thanks
