Summary of the invention
The technical problem that the present invention will solve is, the defective that web page access can not real-time high-efficiency be provided to prior art exists provides a kind of method for caching information.
The present invention provides a kind of method for caching information, and this method comprises the steps:
S1, set up cache information table;
S2, with the identification information of source data and the typing of final updating temporal information to cache information table;
The access request that S3, reception are submitted to generates solicited message;
S4, according to the cache information that whether has said source data in the said identification information judgment local cache, execution in step S4 when not existing, execution in step S5 when existing;
The final updating temporal information that writes down in S5, the identification information that extracts said source data, said source data and the said cache information table generates the data cached of said source data in local cache;
S6, the final updating temporal information of respective identification information in said data cached final updating temporal information and the said cache information table is compared, when the two is consistent, read said data cached.
In method for caching information of the present invention, said source data is stored in the different servers with cache information table.
In method for caching information of the present invention, comprise a plurality of cache information table.
The method for caching information of embodiment of the present invention; Has following beneficial effect: therefore; Those skilled in the art press for develops a kind of under the prerequisite that guarantees the buffer memory instantaneity, effectively improves the website buffer efficiency, and can guarantee the data cached consistency of each client computer.
