Delayed HTTP response is described. In an embodiment, a server device receives a data connection request from a client device and opens a data connection to establish an HTTP communication link to the client device. A first message can be communicated to the client device via the HTTP communication link when the message becomes available. After the first message is returned, the HTTP communication link to the client device is maintained open for communication such that the server device can communicate additional messages to the client device when the additional messages become available at the server device. The messages need not exist or be created at the time of an initial client HTTP request.
