Electronic-messaging system interceptor forwarding client notifications

Abstract

An interceptor, e.g., associated with an electronic messaging (EM) service, transmits a first request to the EM service. The interceptor receives from the EM service a first reply associated with the first request and a notification associated with a client. The interceptor receives, from the client, a second request. The interceptor forwards the second request to the EM service. The interceptor receives from the EM service a second reply associated with the second request. The interceptor creates a modified second reply including at least a portion of the notification by modifying an outer-protocol header of the second reply, an inner-protocol header of the second reply, and an inner-protocol body of the second reply. The interceptor transmits the modified second reply to the client.

What is claimed is: 
     
         1 . One or more non-transitory computer-readable media comprising instructions that are executable by one or more processors to perform operations comprising:
 transmitting a first request to an electronic messaging service;   receiving from the electronic messaging service a first reply associated with the first request and a notification associated with a client;   receiving, from the client, a second request;   forwarding the second request to the electronic messaging service;   receiving from the electronic messaging service a second reply associated with the second request;   creating a modified second reply including at least a portion of the notification by:   modifying an outer-protocol header of the second reply,   modifying an inner-protocol header of the second reply, and   modifying an inner-protocol body of the second reply; and   transmitting the modified second reply to the client.
