1. A method of processing a resource request performed by or for a processor, the method comprising:

  • obtaining a predetermined cookie name responsive to an unencrypted resource request via an indicator of a desired class of service for the unencrypted resource request as a key to access a content addressable memory (CAM) database associating values of the key with predetermined cookie names, resulting in a matching database entry;

    obtaining cookie information from a cookie value associated with a cookie in response to determining that the predetermined cookie name is present in the unencrypted resource request, wherein the cookie is an item of state-related information for insertion into an http object, wherein the cookie information represents a cookie identifier useful for identifying whether a connection exists or recently expired between a client which issued the resource request and a server which originated the cookie;

    providing, as cookie information, a default cookie identifier in response to determining that the predetermined cookie name is absent in the unencrypted resource request;

    obtaining a session identifier from a handshake message relating to the resource request in response to determining that the resource request is an encrypted resource request; and

    obtaining session information from the session identifier corresponding to the encrypted resource request.
