SCRIPT_NAME and PATH_INFO

SCRIPT_NAME and PATH_INFO

[Torsten]

Hello,
I'm currently writing a server handler for a C++ comet server and I'm unsure how to divide a url path into these both variables. Does the sum of both have to be path part of the url (according to rfc3986)? If so, can I choose the SCRIPT_NAME freely and than just fill PATH_INFO with the remaining part and add a '/' if that remaining part is empty? Example:

path: '/' 
   => env['SCRIPT_NAME'] = '/'; env['PATH_INFO'] = '/'

path: '/a/b'
   => env['SCRIPT_NAME'] = '/'; env['PATH_INFO'] = '/a/b'
or  => env['SCRIPT_NAME'] = '/a'; env['PATH_INFO'] = '/b'
or  => env['SCRIPT_NAME'] = '/a/b'; env['PATH_INFO'] = '/'

is this right?

best regards
Torsten

Re: SCRIPT_NAME and PATH_INFO

SCRIPT_NAME is used to mount an app nested somewhere.

If you run for instance a normal Rails or Sinatra app on http://localhost:5000/, then should SCRIPT_NAME == "" and PATH_INFO = "/".

Now if you want to run your Rails app from /foo instead of /, the /foo will be removed from PATH_INFO and added to SCRIPT_NAME.

This is used by so called Rack routers, for instance the `map` method you have in the Rack DSL.
