gnutls https proxy

am writing a https proxy
I am using gnutls to connect to https:www.google.com and I am able to receive the complete response and rendered back to the browser.

Initiallly loop structure
establishing gnu tls session here //need help here -----1
do
{
      select()
    if (browser wannts to talk)
          //in a loop
           then send received request to server
    if (server wants to talk)
           //in a loop
       receive data and sent back to browser
    }while(true)

Initial request is of the form https:www.google.com...and works fine.

After that browser sends another request like
GET https://www.google.com/favicon.ico HTTP/1.1
----

Here I know that web server is not closing the TCP connection because I able  to see in wireshark, But I think gnutls session is closed.

Do some one know...how Rehandshake is established...or conform how the protocal need to work after this step to render the complete google.com page in browser.

I hope session need to be re created (not sure) or use sone method calls like rehandshake to re establish the session.

Please help me regarding this.
