Problems solved by technology

[0003] Existing desktop browsers generally use disk caching, and embedded systems usually do not provide disks due to reasons such as size and cost, and some embedded systems do not even have file systems
[0004] In addition, existing desktop browsers generally do not eliminate infrequently used cached data in time, which consumes system storage resources

Embodiment Construction

[0025] The present invention will be further described below with reference to the drawings and embodiments.

[0026] First embodiment of embedded browser caching device

[0027] figure 1 The principle of the first embodiment of the embedded browser caching device of the present invention is shown. See figure 1 The embedded browser caching device 10 of this embodiment includes an expired data priority elimination module 100 and a low frequency usage priority elimination module 102. The output of the expired data priority elimination module 100 is connected to the low frequency use priority elimination module 102.

[0028] Usually the browser checks the size of the remaining cache space when obtaining network data. If the remaining space is not enough to hold the cached data to be saved, some caches need to be eliminated. Cache elimination should be carried out as much as possible when memory is tight, and the least valuable data should be eliminated in order to maximize the role ...

Abstract

The invention discloses a cache device and a cache method for an embedded browser, which can reasonably buffer network data, reduce storage consumption, fully utilize cached resource and accelerate page view speed. A technical scheme of the invention comprises that: the device comprises an expired data prior eliminating module for acquiring corresponding expired time from a server when the browser acquires the network data, and deleting the expired data when the cache space is insufficient, and a low-frequency utilization prior eliminating module for adding statistics of operating frequency to data in a cache of the embedded browser and deleting data with the lowest operating frequency.

Description

Technical field [0001] The invention relates to a cache strategy of an embedded browser, in particular to an embedded browser cache device and method in the field of web-based digital television two-way interactive applications. Background technique [0002] Cache refers to a buffer for the information data that has been accessed. The browser stores the recently requested pages in the local buffer. When the visitor requests this page again, the browser can obtain the page data locally, which can speed up the browsing of the page. [0003] Existing desktop browsers generally use disk caching. Embedded systems usually do not provide disks due to size and cost. Some embedded systems do not even have a file system. [0004] In addition, existing desktop browsers generally do not eliminate infrequently cached data in time, which consumes system storage resources. Summary of the invention [0005] The purpose of the present invention is to solve the above problems and provide an embedded ...
