Question

Is it possible in a controller to form an absolute uri from the relative path
to another controller action?

In rails application, specifically from a controller,
I am trying to redirect to outside link with a back redirection link set in params,
so that outside application could redirect back to my application at that address.

From ‘mypath/1’ in development environment the function would return

http://localhost/mypath/1

In deployed environment it would return

http://mysite.com/mypath/1

Update:
for my purpose url_for fits well:

url_for :controller => 'tasks', :action => 'testing', :host => 'somehost.org', :number => 
'33'  # => 'http://somehost.org/tasks/testing?number=33'

So, the question’s resolved.

Answer 1

What I was looking is:

url_for :controller => 'tasks', :action => 'testing', :host => 'somehost.org', :number => '33'  # => 'http://somehost.org/tasks/testing?number=33'
