Reading Cookies from another domain?

[Fred Nelson]

Hi:

I have a web app that uses three separate domain names - I am trying to
develop a "single sign on" routine so that they can move between the
sites without having to sign on each time the domain changes.

I have found that I can only read and write cookies based on the URL so
if a cookie is written in "www.domain1.com" it is not available in
"www.domain2.com". I have written a program that does a
Response.Redirect, gets the cookie value and is returned to the sending
domain with a redirect including parameters.

I would like to be able to do this in a class library.

If anyone has any suggestions I would greatly appreciate it!

Thanks,

Fred

Fred,

You might want to consider using passport instead, since it was designed
to handle exactly this scenario.

Hope this helps.
