Environment Variable for Ruby on Rails

[TomRossi7]

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

Is there an entry in the request.env hash for the host header?

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!
