Abstract

Systems and methods for optimized polling. An example method may comprise: receiving, over a transport layer connection, a first application layer request comprising a payload; storing, by a processing device, the payload in a memory; forwarding the payload to an application layer; receiving, over the transport layer connection, a second application layer request comprising no payload; and forwarding the payload to the application layer.

Claims

1. A method, comprising:

receiving, from a client over a transport layer connection, a first application layer request comprising a payload that includes an indication that the client intends to employ an optimized payload transfer mode in which a second application layer request will not include a payload;

in response to detecting the indication in the first application layer request;

storing, by a processing device, a copy of the payload in a memory; and

conveying a response acknowledging the optimized payload transfer mode;

sending the payload to an application layer;

receiving, from the client over the transport layer connection, the second application layer request, wherein the second application layer request pertains to a same communication session as the first application layer request, and wherein the second application layer request does not comprise the payload; and

responsive to receiving the second application layer request, sending the stored payload from the memory to the application layer.

2. The method of claim 1, wherein the transport layer connection is provided by a TCP connection.

3. The method of claim 1, wherein the first application layer request is provided by a first HTTP request and the second application layer request is provided by a second HTTP request.

4. The method of claim 1, wherein the first application layer request comprises a header requesting that the transport layer connection be kept alive.

5. The method of claim 1, wherein the first application layer request and the second application layer request both include data that identifies a same uniform resource identifier (URI), wherein the URI comprises an identifier of a target location on the server where contents of a body of the first application layer request and second application layer request should be placed.

6. The method of claim 1, wherein the first application layer request and the second application layer request comprise a session identifier identifying the same communication session.

7. The method of claim 1, further comprising confirming, to a sender of the first application layer request, that the payload is stored in response to the first application layer request.

8. The method of claim 1, further comprising sending the stored payload from the memory to the application layer responsive to receiving a subsequent application layer request pertaining to the same communication session.

9. A method, comprising:

transmitting, from a client over a first transport layer connection, a first application layer request to a server, the first application layer request comprising a payload and an indication in the request that the client intends to employ an optimized payload transfer mode in which a second application layer request will not include a payload, wherein the indication is configured to cause the server to store a copy of the payload in a memory and send the stored payload to an application layer responsive to receiving the second application layer request that does not include the payload;

in response to the first application layer request, receiving from the server an indication that the server accepts the optimized payload transfer mode;

transmitting, over the transport layer connection, the second application layer request comprising no payload, wherein the second application layer request pertains to a same communication session as the first application layer request.

10. The method of claim 9, wherein the transport layer connection is provided by a TCP connection.

11. The method of claim 9, wherein the first application layer request and the second application layer request both include data that identifies a same uniform resource identifier (URI), wherein the URI comprises an identifier of a target location on the server where contents of a body of the first application layer request and second application layer request should be placed.

12. The method of claim 9, wherein the first application layer request comprises a header requesting that the transport layer connection be kept alive.

13. A computer system comprising:

a memory; and

one or more processors, coupled to the memory, to;

receive, from a client over a transport layer connection, a first application layer request comprising a payload that includes an indication that the client intends to employ an optimized payload transfer mode in which a second application layer request will not include a payload;

in response to detecting the indication in the first application layer request;

store a copy of the payload in the memory; and

convey a response to the client acknowledging the optimized payload transfer mode

send the payload to an application layer;

receive, from the client over the transport layer connection, the second application layer request, wherein the second application layer request pertains to a same communication session as the first application layer request, and wherein the second application layer request does not comprise the payload; and

responsive to receiving the second application layer request, send the stored payload to the application layer.

14. The computer system of claim 13, wherein the processors are further to:

send the stored payload from the memory to the application layer responsive to receiving a subsequent application layer request pertaining to the same communication session.

15. A computer-readable non-transitory storage medium comprising executable instructions that, when executed by a computer system, cause the computer system to perform operations comprising:

receiving, from a client over a transport layer connection, a first application layer request comprising a payload that includes an indication that the client intends to employ an optimized payload transfer mode in which a second application layer request will not include a payload;

in response to detecting the indication in the first application layer request;

storing a copy of the payload in a memory; and

conveying a response acknowledging the optimized payload transfer mode;

sending the payload to an application layer;

receiving, from the client over the transport layer connection, the second application layer request, wherein the second application layer request pertains to a same communication session as the first application layer request, and wherein the second application layer request does not comprise the payload; and

responsive to receiving the second application layer request, sending the stored payload from the memory to the application layer.

16. The computer-readable non-transitory storage medium of claim 15, further comprising executable instructions that cause the computer system to perform operations comprising:

sending the stored payload from the memory to the application layer responsive to receiving a subsequent application layer request pertaining to the same application layer session.
