HTTP session ID is an optional non-negative integer which is attached to +the session and any sockets it creates. The session ID is set on sockets by +using RSocket::SetOpt().

+

With this session ID, clients can specify an integer ID for an HTTP session, +which is assigned to subsequent sockets. An ID that is set applies to subsequent +socket connections.

+

HTTP session ID can be accessed using a Flow hook implementing the SetFlowOption() method, +which is called whenever RSocket::SetOpt() is called. The +Flow hook helps determine if a socket came from a specific session.

+

The session ID is set when the socket is created and is not changed. To +find the session ID of a socket, the flow object must look for Set Option +commands that request setting session ID. The ID that is set can be saved +in the Flow hook object, and used later when needed. This can be done using +an iSessionId variable to hold the value, as shown in the +following example:

+#include <HTTPSocketConstants.h> // option consts defined here.... +class CMip4Protocol : public CIp6Hook +{ +public: +... +virtual TInt SetFlowOption(TUint aLevel, TUint aName, const TDesC8 &aOption, CFlowContext &aFlow); +private: +... +TInt iSessionId; // session ID is stored here. Should be initialized to KErrNotFound +}; +

The HTTP session ID, HTTP::ESessionId, when set, is accessed +using the session’s connection info object. For example:

+RHTTPSession session; +... +RHTTPConnectionInfo ConnectionInfo = session.ConnectionInfo(); + +

To access the value, RString must first be extracted from +the string pool. For example:

+RStringF sessionId = session.StringPool().StringF(HTTP::ESessionId, RHTTPSession::GetTable()); +sessionId.Close(); + \ No newline at end of file
