CN101557390A - Method for improving system performance by flexibly using cache technology - Google Patents

Abstract

A method for improving system performance by flexibly using a cache technology comprises the following steps: firstly, a client terminal sends a request for downloading sources to a server and appoints a source ID; the server uses the source ID as a cache name to check whether a source exists in a cache, and if the source does not exists in the cache, the server loads the source from a database or other source servers; the servers select a proper overdue policy for the source; the server adds the source to the cache and appoints a reasonable overdue mode; the server returns the source as responsive data to the client terminal; the client terminal sends a request for downloading the source to the server again; the server checks whether the cache exists in the existing cache or not, and if the cache exists, the server checks whether the cache is overdue according to the overdue mode; if the cache is not overdue, the server directly returns the source as a response to the client terminal; and finally, the cache is automatically and regularly cleared to release some overdue sources. The invention flexibly uses the cache technology to improve the system performance.

Description

A kind of caching technology of applying in a flexible way improves the method for systematic function

Technical field

The present invention relates to the method that a kind of caching technology of applying in a flexible way improves systematic function, particularly a kind of the employing uses caching technology to improve the method for systematic function in the software development.

Background technology

Provide when service at server to client, use caching technology can buffer memory to live in the result of time computing, when receive client-requested next time, will not need computing once more, will significantly improve systematic function.Buffer memory needs expired time, and the expired mode of buffer memory need be configured neatly, in the design of buffer memory, should take out interface expired time as a kind of strategy, is convenient to expand neatly.Need a kind of interface that can check buffer memory, so that carry out the tuning of buffer memory.

Summary of the invention

Technical problem to be solved by this invention provides a kind of the employing and uses caching technology to improve the method for systematic function in the software development.

A kind of caching technology of applying in a flexible way of the present invention improves the method for systematic function, and this method comprises following step at least:

Step 1: user end to server is initiated the request of downloaded resources, and allocated resource ID.

Step 2: server as the buffer memory title, checks in the buffer memory whether this resource is arranged with resource ID, if this resource not then loads from database or other Resource Server.

Step 3: server is the suitable expired strategy of this resource selection.

Step 4: server is added to this resource in the buffer memory, and is appointed as rational expired mode.

Step 5: server returns to client to resource as reply data.

Step 6: client is initiated the request of downloaded resources once more to server.

Step 7: server checks in the buffer memory whether this buffer memory is arranged, if this buffer memory is arranged, then checks according to expired mode whether it is expired.

Step 8: expired if buffer memory does not have, then directly this resource is returned to client as replying.

Step 9: regularly clear up buffer memory automatically, discharge some expired resources.

A kind of caching technology of applying in a flexible way of the present invention improves the method for systematic function, and server the steps include: for the suitable expired strategy of this resource selection

Step 31:, can be appointed as never expired buffer memory in program running if this resource can not change all the time.

Step 32:, then can specify expired buffer memory of set time after the duration of an appointment if this resource may change.

Step 33: if this resource depends on a file modifying time, for example this resource loads from this document, can be appointed as the buffer memory that relies on the file modification time.

Step 34: can according to circumstances specify the more buffer memory of science, for example short expired time can be set when beginning, along with the frequent degree of its visit constantly increases expired time.

Step 35:, can various expired modes be grouped together neatly by integrated mode if this buffer memory depends on above-mentioned multiple expired mode simultaneously.

A kind of caching technology of applying in a flexible way that the present invention relates to improves the method for systematic function, and the feasible caching technology of applying in a flexible way improves systematic function.

Description of drawings

Fig. 1 is a flow chart of the present invention.

Embodiment

Referring to Fig. 1, key step of the present invention is as follows:

Step 1: user end to server is initiated the request of downloaded resources, and allocated resource ID.

Step 2: server as the buffer memory title, checks in the buffer memory whether this resource is arranged with resource ID, if this resource not then loads from database or other Resource Server.

Step 3: server is the suitable expired strategy of this resource selection.

Step 4: server is added to this resource in the buffer memory, and is appointed as rational expired mode.

Step 5: server returns to client to resource as reply data.

Step 6: client is initiated the request of downloaded resources once more to server.

Step 7: server checks in the buffer memory whether this buffer memory is arranged, if this buffer memory is arranged, then checks according to expired mode whether it is expired.

Step 8: expired if buffer memory does not have, then directly this resource is returned to client as replying.

Step 9: regularly clear up buffer memory automatically, discharge some expired resources.

Above-mentioned steps 3 servers are that the concrete steps of the suitable expired strategy of this resource selection are as follows:

Step 31:, can be appointed as never expired buffer memory in program running if this resource can not change all the time.

Step 32:, then can specify expired buffer memory of set time after the duration of an appointment if this resource may change.

Step 33: if this resource depends on a file modifying time, for example this resource loads from this document, can be appointed as the buffer memory that relies on the file modification time.

Step 34: can according to circumstances specify the more buffer memory of science, for example short expired time can be set when beginning, along with the frequent degree of its visit constantly increases expired time.

Step 35:, can various expired modes be grouped together neatly by integrated mode if this buffer memory depends on above-mentioned multiple expired mode simultaneously.

Above-mentioned technical scheme provides a kind of caching technology of applying in a flexible way to improve systematic function when implementing.

It should be noted last that above embodiment is only in order to explanation and unrestricted technical scheme described in the invention; Therefore, although this specification has been described in detail the present invention with reference to the above embodiments,, those of ordinary skill in the art should be appreciated that still and can make amendment or replacement to the present invention with being equal to; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in the middle of the claim scope of the present invention.

Claims (2)
