Embodiment Construction
[0029] Embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0030] Aiming at the problems of inefficient deletion operation and lower cache performance existing in the existing WEB cache replacement technology, the embodiment of the present invention provides a method and device for WEB cache replacement, HTTP, and a proxy server to solve the problem .
[0031] In the technical solution of the embodiment of the present invention, two storage mechanisms and one deletion mechanism are proposed. The two storage mechanisms include cache partition storage and name-corresponding storage, and the deletion mechanism is a batch deletion mechanism.
[0032] The partition storage mechanism includes: dividing the cache space into at least two subspaces, storin...

The invention discloses a method and device for replacing WEB caches and an HTTP proxy server to solve the problems that according to an existing WEB cache replacing technology, the efficiency of the deletion operation is low, and the cache performance is lowered. According to the embodiment, the cache space is divided into at least two subspaces through the HTTP proxy server, files are sequentially stored in the subspaces of the cache space according to the time sequence, and another subspace serves as a new current subspace when the current subspace is not provided with a vacant storing space. When the subspaces are full, all files in the subspace which becomes full first are deleted, the files can be deleted in batches under the condition that the cache hit rate is guaranteed, the efficiency of the deletion operation in the process of replacing the WEB caches can be obviously improved, the effect on the reduction of the cache performance is little, and the problems that according to the existing WEB cache replacing technology, the efficiency of the deletion operation is low and the cache performance is lowered can be effectively solved.
Description
technical field [0001] The present invention relates to a network communication system, in particular to a WEB cache replacement method and device, and a hypertext transfer protocol (HTTP, Hyper Text Transfer Protocol) proxy server. Background technique [0002] The normal HTTP access process is a typical client and server model, such as figure 1 As shown, the user uses the client program on the computer, such as a browser, to send a request, and the remote WEB server program responds to the request and provides corresponding data. The HTTP proxy server is between the client computer and the WEB server, and forwards the request and data. For the WEB server, the HTTP proxy server is the client, and the HTTP proxy server forwards the request from the client to the WEB server, and the WEB server responds to the request; for the client, the HTTP proxy server is the WEB server, which accepts the request from the client request, and transfer the data uploaded from the WEB server ...
