Web Cache (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A web cache is a mechanism for the temporary storage (caching) of web documents, such as HTML pages and images, to reduce bandwidth usage, server load, and perceived lag. A web cache stores copies of documents passing through it; subsequent requests may be satisfied from the cache if certain conditions are met.It should not be confused with a web archive, a site that keeps old versions of web pages.
