embedding the mapping information with the client state information.

13. The method of claim 12 , further comprising:

in response to the push notification, receiving, from the client device, a request for the resource and a request for client state information on a pull transaction, wherein the request for client state information includes the user identification;

comparing the user identification to current user information to determine if the user identification corresponds to the current user information;

if it is determined that the user identification corresponds to the current user information:

removing the user identification from the request for client state information; and

transmitting the request for the resource and the request for client state information to the resource host, and

if it is determined that the user identification does not correspond to the current user information:

denying the request for the resource and issuing an error, or

transmitting the request for the resource but not the request for client state information to the resource host.

14. The method of claim 13 , wherein the current user information includes at least one of a logical address of a current user and authentication information of the current user.

15. The method of claim 13 , wherein the receiving, comparing, removing, transmitting the request for the resource and the request for client state information, denying, and transmitting the request for the resource but not the request for client state information, are performed by a wireless application gateway.

16. The method of claim 6 , wherein the information for initiating a cookie session is a cookie header within an HTTP headers section of the push message.

17. A method comprising:

receiving a push message including:

a push notification that indicates a link to a resource on a resource host, and

client state information including information for initiating a cookie session;

reading the client state information; and

associating the client state information with the link to the resource.

18. The method of claim 17 , wherein the receiving, reading, and associating is performed by a client device.

19. The method of claim 17 , wherein the client state information includes metadata specifying a push notification initiator, and wherein associating comprises:

storing the client state information;

forming a request for client state information for a pull transaction based on the metadata included in the received client state information; and

transmitting a request for the resource and the request for client state information to a wireless application gateway based on activation of the link to the resource.

20. The method of claim 17 , wherein the information for initiating a cookie session is a cookie header within an HTTP headers section of the push message.

21. A processing system comprising:

a processor; and

a memory containing instructions, which, when executed by the processor, cause the processing system to perform a method comprising:

forming a push message including:

a push notification that indicates a link to a resource on a resource host, and

client state information including information for initiating a cookie session; and

pushing the push message.

22. The method of claim 21 , wherein the information for initiating a cookie session is a cookie header within an HTTP headers section of the push message.

23. A processing system comprising:

a processor; and

a memory containing instructions, which, when executed by the processor, cause the processing system to perform a method comprising:

receiving a push message including:

a push notification that indicates a link to a resource on a resource host, and

client state information including information for initiating a cookie session;

processing the push notification and client state information; and

transmitting the push message to a client device.

24. The processing system of claim 23 ,

wherein the client state information includes metadata specifying an intended application on the client device to receive the push notification.

25. The processing system of claim 23 wherein the client state information includes metadata specifying an intended receiving user and processing the push notification and the client state information comprises:
