Abstract

Provided is a method of improving performance of a web server by predicting a Hypertext Transfer Protocol (HTTP) request and the web server enabling the method, including transmitting, to an HTTP requester, at least one web content among web contents including static web contents and dynamic web contents in response to an HTTP request, selecting, from the web contents, a required web content to be additionally transmitted to the HTTP requester and a potential web content to be additionally transmitted to the HTTP requester, determining, among the potential web content, a web content to be preloaded, and storing, in a document cache, the required web content and the web content to be preloaded.

Claims

1. A method of improving performance of a web server based on prediction of a Hypertext Transfer Protocol (HTTP) request, the method comprising:

transmitting, to an HTTP requester, at least one web content among web contents comprising static web contents and dynamic web contents, in response to an HTTP request;

selecting, from the web contents, a required web content to be additionally transmitted to the HTTP requester and a potential web content to be additionally transmitted to the HTTP requester;

determining, among the potential web content, a web content to be preloaded; and

storing, in a document cache, the required web content and the web content to be preloaded.

2. The method of claim 1, further comprising:

registering the web contents, and

wherein, when a web content to be registered is a static web content, the registering comprises;

analyzing a substance of the static web content to be registered;

extracting, based on the analyzed substance of the static web content, information necessary to select, from the web contents, the required web content and the potential web content; and

storing the extracted information in a lookup table.

3. The method of claim 2, wherein, when the at least one web content to be transmitted to the HTTP requester is the static web content, the selecting comprises:

extracting, based on the lookup table, the required web content and the potential web content.

4. The method of claim 1, wherein, when the at least one web content to be transmitted to the HTTP requester is a dynamic web content, the selecting comprises:

analyzing a substance of the at least one dynamic web content to be transmitted to the HTTP requester; and

extracting, based on the analyzed substance of the at least one dynamic web content, the required web content and the potential web content.

5. The method of claim 1, wherein the determining is performed based on at least one of memory occupancy of the document cache and an HTTP request frequency.

6. The method of claim 1, wherein the storing comprises:

searching the document cache for the required web content and the web content to be preloaded;

loading, when at least one of the required web content and the web content to be preloaded is determined to be absent in the document cache as a result of the searching, the at least one web content absent in the document cache from an auxiliary memory; and

storing the loaded web content in the document cache.

7. The method of claim 1, wherein the storing is performed asynchronously with the transmitting.

8. The method of claim 4, wherein the selecting is performed during a runtime delay caused by transmission of the at least one dynamic web content to the HTTP requester.

9. A web server, comprising:

an auxiliary memory;

a memory comprising a document cache;

a network interface to perform communication with an HTTP requester;

a web content transmitter to transmit, to the HTTP requester, at least one web content among web contents comprising static web contents and dynamic web contents, in response to an HTTP request;

a web content selector to select, from the web contents, a required web content to be additionally transmitted to the HTTP requester and a potential web content to be additionally transmitted to the HTTP requester;

a preloading web content determiner to determine, among the potential web content, a web content to be preloaded; and

a document cache storage unit to store, in the document cache, the required web content and the web content to be preloaded.

10. The web server of claim 9, further comprising:

a web content registerer to register the web contents, and

wherein, when a web content to be registered is a static web content, the web content registerer comprises;

a static web content analyzer to analyze a substance of the static web content to be registered;

a selection information extractor to extract information necessary to select, from the web contents, the required web content and the potential web content, based on the analyzed substance of the static web content; and

a lookup table storage unit to store the extracted information in a lookup table.

11. The web server of claim 10, wherein, when the at least one web content to be transmitted to the HTTP requester is the static web content, the web content selector comprises:

a static web content extractor to extract, based on the lookup table, the required web content and the potential web content.

12. The web server of claim 9, wherein, when the at least one web content to be transmitted to the HTTP requester is a dynamic web content, the web content selector comprises:

a dynamic web content analyzer to analyze a substance of the at least one dynamic web content to be transmitted to the HTTP requester; and

a dynamic web content extractor to extract, based on the analyzed substance of the dynamic web content, the required web content and the potential web content.

13. The web server of claim 9, wherein the preloading web content determiner determines the web content to be preloaded based on at least one of memory occupancy of the document cache and an HTTP request frequency.

14. The web server of claim 9, wherein the document cache storage unit comprises:

a web content searcher to search the document cache for the required web content and the web content to be preloaded;

a web content loader to load, when at least one of the required web content and the web content to be preloaded is determined to be absent in the document cache as a result of the searching, the at least one web content absent in the document cache from the auxiliary memory; and

a storage unit to store the loaded web content in the document cache.

15. The web server of claim 9, wherein the document cache storage unit is performed asynchronously with the web content transmitter.

16. The web server of claim 12, wherein the web content selector selects, among the web contents, the required web content and the potential web content during a runtime delay caused by transmission of the at least one dynamic web content to the HTTP requester.
