Session problem..... urgent

[Anon]

I have a page "A" which sets a session var.
The next line on this page changes the document location to another page "B" in another directory. In page "B" when I check to see if the session var set in page "A" is available I get a null value .
Help me with this ...

Also What does the following mean

session.save_path = /tmp

session.cookie_path =

session.cookie_domain =

Does cookie_path have to be the same as save_path

Thanks a lot

This is getting to be a question of the week.

Loook through the forum to see.. well, many examples of how to use sessions properly.

PS No code-sample, no help.
