What is web cache?
Web cache is a file folder in a web browser that stores data from the website that the user visits. Provides a way to quickly display web content from the site that the user has previously visited and stores images, web scripts, multimedia files and other website content. Both web browsers and proxy servers implement cache, which can shorten the time required to obtain information, reduce network load, reduce data transfer costs and improve network accessibility.
The most common type of web cache is a browser cache that stores images, streaming video, cascading styles (CSS) files that appear on the website. When the user visits the web, the browser first searches for the content in the browser cache. If the user has already visited the site, the cache usually contains a stored copy of the site content, so the browser does not have to download the page from the web server. Material in the cache has expired validatum to ensure thatThe user will not view obsolete content. When the content of the accessible website changes, the website data data will also be updated to reflect these changes.
In networks that implement proxy server, there is another type of web cache. When a user navigates the site in their browser, a proxy server is submitted to check that this particular site will already appear in the cache. The Proxy Server cache contains data from the website visited by all network users. If the material already exists in the cache and is not outdated, it will not have to be withdrawn from the Internet again. The data on the cache in the local area can help improve the availability and efficiency of network with high transport or limited bandwidth.
both types of web cache have their own advantages and disadvantages. Browser cache and proxy server cache both alnocking users forFaster access to website data. The proxy server cache is particularly useful for large networks that have many users, provide limited bandwidth, experience high data utilization and implement streaming video or voice via the Internet protocol (VOIP). If the material is not updated quickly enough and if it is not configured on the cache of certain types of data, the disadvantages may have disadvantages if the material is not updated quickly enough and unless it is configured to cache certain types of data. The cache can also be completed quickly if only a small amount of space is available.
