Abstract

Methods and systems for a client such as a web browser to access the services of a server such as a web server are disclosed. In one embodiment, a method implemented by a client to transmit service requests to a server includes, transmitting a first service request over a persistent-connection to the server, detecting a beginning of a response to the first service request from the server, and transmitting a second service request to the server after the beginning of the response is detected. The client can be a web browser, and the server can be a web server. The first and second service requests, as well as the response to the first service requests may be transmitted over a persistent connection.

Claims

1. A method for a client to transmit service requests to a server, the method comprising:

transmitting a first service request to the server, wherein the first service request is transmitted over a persistent-connection;

detecting a beginning of a first response from the server, wherein the first response is associated with the first service request; and

transmitting a second service request to the server after the beginning of the first response is detected, wherein the second service request is transmitted over the persistent-connection.

2. The method of claim 1, wherein the first response from the server is received on the persistent-connection.

3. The method of claim 1, wherein the first service request, the first response, and the second service request are HTTP messages.

4. The method of claim 1, wherein the detecting step comprises:

monitoring the persistent-connection; and

locating a partial-response from the server, wherein the partial-response is part of the first response.

5. The method of claim 4, further comprising:

determining, based on the partial-response, that the server is active.

6. The method of claim 4, further comprising:

determining, based on the partial-response, that the persistent-connection is active.

7. The method of claim 4, wherein the locating step comprises:

identifying a beginning header of the first response; and

identifying an ending header of the first response.

8. The method of claim 1, wherein the second service request transmitting transmits the second service request before the first response is completely received.

9. A client device, comprising:

at least one processor;

a memory; and

a web browser coupled to the memory and the at least one processor, the web browser comprising a pseudo pipeline controller configured to;

transmit, using the at least one processor, a first service request to a server, wherein the first service request is transmitted over a persistent-connection;

detect, using the at least one processor, a beginning of a first response from the server, wherein the first response is associated with the first service request; and

transmit, using the at least one processor, a second service request to the server after the beginning of the first response is detected, wherein the second service request is transmitted over the persistent-connection.

10. The client device of claim 9, wherein the first service request, the first response, and the second service request are HTTP messages.

11. The client device of claim 10, wherein the second module is further configured to:

monitor the persistent-connection; and

locate a partial-response from the server, wherein the partial-response is part of the first response.

12. The client device of claim 9, wherein the second service request is transmitted before the first response is completely received.

13. A tangible computer program product comprising a computer readable medium having computer program logic recorded thereon for causing at least one processor to:

transmit a first service request to the server, wherein the first service request is transmitted over a persistent-connection;

detect a beginning of a first response from the server, wherein the first response is associated with the first service request; and

transmit a second service request to the server after the beginning of the first response is detected, wherein the second service request is transmitted over the persistent-connection.

14. The tangible computer program product of claim 13, wherein the first service request, the first response, and the second service request are HTTP messages.

15. The tangible computer program product of claim 13, wherein the second program logic further causes the at least one processor to:

monitor the persistent-connection; and

locate a partial-response from the server, wherein the partial-response is part of the first response.

16. The tangible computer program product of claim 13, wherein the second service request is transmitted before the first response is completely received.
