Hello,  
I am trying to pass a uID($uid\_got value) that has been generated  
by Nginx httpuseridmodule to my sinatra app.

Basically I could have taken from the cookie but the cookie does not get  
set on the browser unless the response headers have been sent back.

Can anyone give any suggestions regarding that?

Thanks,  
Dhaval.
