How do handle Dynamic values (correlation ) for websocket protocol

Hi team,

I am recording an application which communicates Websockets for its communication. 

I do see there are few session ids and cookie values in the action.c , and the same cookie and session are assigned by the tool at the time of recording to an array in websocketbuffer.h 

I need to understand how to handle correlation for this values? where should i place the correlation function?

Also the  session value is being passed into the header  first and  i am not finding the boundaries to place it .

Are there any videos that helps me to understand the webocket protocol.

Regards,

Sagar.
