Hi folks
I've got secure login areas on two different sites - one is built in asp.net and the other in php (and each on a different server). User credentials are valid for both sites, i.e. if you register on one site, your username and password will be valid on the other site too.
Currently a user may only navigate from the asp.net site to the php site. I did this in a rush, and could only think of passing variables through a querystring - as a result (although I pre-populate the username field on the php site) I have to force the user to re-enter their password. This is clearly not ideal.
I don't suppose there's a way to share session information between asp.net and php? Or at least, post variables between the two platforms? If I managed to do so, would it be a security risk? And what if I want to pass login information back the other way (i.e. from php to asp.net)?
Please tell me if I'm dreaming.
Cheers!
