When are Session variables...available?

[jsteph]

Hi,
I'm having a problem dealing with session variables. I have a page that calls another page.

In Global.asa Session_OnStart I have:
session("FOO") = ""

Page 1 does:
session("FOO") = "bar"

Page 2 says:
response.write session("FOO")

Page 2 is blank--why? If, in Page 1, prior to calling Page 2, I do:
response.write session("FOO"), I get 'bar' on page 1.

I've checked the sessionID of both pages and they are of the same session. What's going on here??
Thanks,
--Jim

Never Mind...
It *is* a different sessionID. I don't know how or why, but it seems that ASP or IIS or whatever just starts a new session when I call the other page.

Two reasons, generally (assuming timeout is not an option):
1) The cookie that holds the SessionID from IIS is not getting saved, thus you get a new one with each page load
2) Your using full URL's to go from page to page (rather than relative addresses) and your going from

http://www.yourdomain.com/

to

http://yourdomain.com/

(this matters for the cookies again)

tarwn,
Thanks, I think that is it. This is an intranet, but we can call this page by any of the below:

http://server/webapp/startpage.asp

http://server.ad.company.com/webapp/startpage.asp

http://server.company.com/webapp/startpage.asp

http://server.anycompanyalias.com/webapp/startpage.asp

...so, the cookies use the literal domain and *not* the resolved IP address? I'm hoping it's at least case insensitive?

I am not actually sure about the case thing. That may be up to the browser, but I would assume it would be case insensitive.

If they did use the IP adddress, think about how much private information I could gather just by parking a few ASP scripts on an ISP next to an e-store and just reading all ofthe cookies that the browser sent me...it wouldn't be pretty.

Tarwn your case temp is hotter than your CPU temp?
