Share a cookie between two websites

by

No. Website B can’t read a cookie from website A.

The easiest work-around is to pass login/credential information from website A to website B and have website B set a seperate cookie. For example, after logging into website A you could have them quickly redirected to website B with an encrypted querystring. Website B could then read the information, set its own cookie, and redirect the user back to site A.

It’s messy but possible.
