Custom header items are not used for sending GET/POST requests

What steps will reproduce the problem?
1. Select site that uses Authentication token from cookies (after initial 
authentication, cookie is given by server)
2. In advanced rest client use GET and add custom header..Set Cookie, 
User-Agent etc..
3. Send request.

What is the expected output? What do you see instead?
- During request, Chrome should have used header elements from custom header.
Instead, Chrome uses different cookie as well as User-Agent values..
(Due to that it some time ask for re-authentication)

On what operating system, browser and browser version?
Windows-7.. Browser Chrome: Version 35.0.1916.114 m
