Environment Variable for Ruby on Rails

Is there an entry in the request.env hash for the host header? I can
parse the request.env["REQUEST_URI"], but I was just wondering. I
couldn't find any documentation on the contents of that hash --
http://api.rubyonrails.com/classes/ActionController/Base.html appears
to only show a couple of the keys.

Thanks!
Tom

request.host is the method you're looking for. See the docs for
AbstractRequest for some other convenient methods such as subdomains
and remote_ip (which resolves proxied addresses for you.)

You can use the magical .inspect on the request.env hash like so:
request.env.inspect to find out anything about the internals of a hash.

script/console will work pretty well for that kind of debugging.

Warmest regards,
Nathan.

..inspect is very useful indeed! Thanks!

Perfect! Unfortunately, I can't seem to find the documentation though
for it?
http://api.rubyonrails.org/classes/ActionController/AbstractRequest.html
talks about some methods, but not request.host.

The only reason I ask is because now I want to pull back the Session
Id. I don't see a straight-forward way to get it?

Thanks,
Tom

An oversight; its documentation is exposed the next release.

In a controller, session.session_id

Please take further discussion to the Rails list. Thanks!
