How to set httpHeader in response object

Hi All,

We have requirement to pass the user name from java application to OBIEE server for authentication.
We are trying to pass user name using below code.

response.setHeader("REMOTE_USER", userId);
response.sendRedirect(URL);

But the OBIEE which is installed in another machine is not able to get the this user name.
Is this the correct way to set the httpHeader to response object?

Regards
Shyam
