Disk caching method for embedded browser

Abstract

The invention provides a disk caching method for an embedded browser. In the method, the embedded browser takes a caching medium as a disk. The method comprises the following steps of: storing webpage resources accessed by a user onto a disk medium; establishing a mapping relationship between a resource URL (uniform resource locator) and disk caching data, and recording and maintaining the mapping relationship between the resource URL and the disk caching data on the disk medium; accessing the webpage resources according to the recorded mapping relationship, and querying from the mapping relationship when the resource URL is accessed; if a corresponding mapping value is found, determining that resources are stored on the disk, and reading the webpage resource data from the disk medium; and otherwise, downloading required webpage resource data from a server. The step of establishing the mapping relationship comprises the following substeps of: obtaining a Hash value of the resource URL by adopting a Hash algorithm; and writing a key value pair formed by the resource URL and the Hash value into a disk caching retrieval table to establish the mapping relationship between the resource URL and the disk caching data.

Description

technical field [0001] The invention relates to the field of embedded technology, in particular to an embedded browser disk caching method. Background technique [0002] In an embedded system, especially in an Internet TV set-top box as a triple play terminal, the embedded browser may become the most important application software of the embedded operating system, and may even be the only application software that directly supports interaction with users. In this case, the access speed of the embedded browser directly affects the user experience. Caching is to store the information that the user has accessed locally, so as to improve the speed when the user accesses relevant information again. The existing patents on embedded browser caching are all based on memory caching, which is determined by the application scenario of small business volume and small hard disk capacity in the early stage of embedded browser application. With the integration of three networks, Internet ...

Problems solved by technology

The existing patents on embedded browser caching are all based on memory caching, which is determined by the application scenario of small business volume and small hard disk capacity in the early stage of embedded browser application. With the integration of three networks, Internet TV set-top boxes have emerged. Embedded terminals with a large amount of business and large hard disk capacity, so the current embedded browser that only uses memory for network resource caching is far from meeting the new needs
