Re: Changing the location of a different frame with CGI

I ... would like to change the location of more than one frame on a web page when a logoff occurs.

There are two ways to do this.

Reload the entire page, producing revised frame contents when you do, or
Use JavaScript to reach out and reload other frames (by changing their location.href properties).

Of these, the first is the safest.

It's also interesting to note that the second option triggers some particularly unfortunate browser behaviour. I worked on an extranet application once where this was done and it turns out that the browsers back button would undo exactly one assignment to the location.href properties. The net effect was that the users had to click back three> times to go back one actual page. It was ugly and I wish that on no one. Summary: follow dws first suggestion or suffer the consequences. Meohahaha! (ok so I've got a super-kitty villan flick on right now, sue me) `__SIG__ use B; printf "You are here %08x\n", unpack "L!", unpack "P4", pack "L!", B::svref_2object(sub{})->OUTSIDE;` [download]	[reply] [d/l]
