passing information between webpages using cookie

[Song Zhang]

I have two webpage, one is http://appA.mycompany.com/first.html and the
other is http://appB.mycompany.com/second.html

When a user visits first.html, he may click a button A, which launches
second.html. In second.html, there is a button, if clicked, a cookie is set
with “mycookie=ok;do main=.mycompany .com”.

At first.html, I have a function that keeps checking cookie with name
mycookie. If mycookie is set, an alert window is started to show the value
of mycookie.

My question is principally, is this doable? Thx in advance.

Technically, yes. However, it only works if the user's browser allows
cross-domain cookies, and not all browsers (or users) do that.

It is, however, probably your only chance of communicating between
pages in different domains.

Re: passing information between webpages using cookie

How about if you use a HTA as your host and open each page in its own frame? I haven't done exactly
what the OP is asking, but similar to what I am describing. When you open each page, set a handle
to the window and just use a variable and I suppose a timer in the HTA to keep checking for a change
in the value of the variable.

Re: passing information between webpages using cookie

This is not really a cross-domain cookie, it's a domain-wide cookie.
Most browsers allow this by default. What Song is proposing will work,
if he can write the Javascript timer code appropriately in first.html
(e.g. go to sleep for 1 second, try reading the cookie, etc.).
