What is saving in the proxy server cache?

Server cache cache is used to shorten the time required for users in computer networks to access content on the Internet. If the network administrators enable the cache saving, the proxy server often saves accessible content, so it does not have to download the content from the Internet every time the user asks it. When a user enters a web address in a web browser, the request goes to the Proxy server that is looking for the specified material in its cache. If the information you require cannot be found, it will send an application to the Internet. This can save the bandwidth and shorten the time when the user has to wait for content. If the proxy server cannot find the desired site in its cache and then downloads a new copy from the web server, it performs passive storage in the cache. The cache storage is active when the server is inactivity and cache web pages that users often approach the network. By enabling activity of storage in the cache, network administrators can ensure that the proxy server has a new copy of the content. NThe evidence of active cache storage is that it may require a larger bandwidth and may not be suitable for servers that have a bandwidth or required downtime.

Data stored from saving server storage is not permanent and must be updated regularly to ensure that users get the latest version of the content. Although the cache objects need to be updated when the content of the website changes, they also have time of expiry. When the item expires, the proxy server checks with the web server and get information about the latest version of the content. If there is a change, it will download a fresh copy; Otherwise, the content may not download the content again and only updates the expiry time. Proxy servers maintain the protocol of these actions so that administrators can view how often the server grabs new content AJAK often users approach the content directly from the cache.

proxy mThe server's ezipama has the disadvantage of sometimes damage to network performance. If the network administrator assigns too little space to store the server, the server will need to remove the items from the cache. Items that are least used or first to expire will usually be removed first to create space for additional items when it is needed
