/*
======================================================================
The following apex code demonstrates logging into another salesforce
org via the SOAP/XML web service api and then using session id to
query the standard REST API as well as the Chatter REST API.
To run this code, simply copy and paste into execute anonymous,
then replace the value of the first three variables accordingly.
NOTES:
(1) You'll need to create a remote site setting for both the login
url and the server url. If you're org is on na1, then you'll
need the following URLs as remote site settings:
https://www.salesforce.com
https://na1-api.salesforce.com
