Login to multiple subdomains, one chili instance

Added by André Cardoso at 2011-09-17 04:42 pm

Hi. I have a problem here :)

I've successfully installed chili. Now, I've also created a bunch of projects which I'd like to make available on specific subdomains.
So I've managed to work with apache's mod_rewrite in order to redirect the project's url to another subdomain. For example:

http://main.com --> http://main.com
http://main.com/projects/xpto --> http://xpto.main.com/projects/xpto

Despite the usefulness of what I've done with the rules, I wanted to know how to solve a specific problem:
- The redirects work, but they ask me for login whenever I change domain. Is there a way to avoid this? From the moment I login on "main.com" I want to be automatically logged in onto the sub-domains.

Can this be accomplished?

Thank you in advance!
André

This is a problem with how cookies work: You can't access a cookie for a domain from a subdomain, i.e. you can't access for foo.com when you visit bar.foo.com. In general, you can only set cookies for your host and can only access those, one exception being that subdomains can "share" cookies, i.e. bar.foo.com and baz.foo.com can set and access cookies to .foo.com.

Can this be accomplished?

Probably, but it seems like the wrong answer to whatever problem you are trying to solve.

It might work if you force the domain of the cookie in your config to .main.com and change your landing domain to www.main.com so that it is a subdomain too.
