For years, technology products have used caching to bring high performance. Simply put a cache becomes most of the time, the final solution to increase the performance of a data request. Page and DNS Caching are now critical for all operations in the wired space. Recently caching became really popular for Database access management.

Caching provides two key benefits for Internet users

• Reduce latency – Though the requests satisfy from the cache, which is closer to the client, caching reduces the overall network latency and returns much faster pages to the browsers.
• Reduce network traffic – Caching, for some extent reduces the network bandwidth requirement as much as 35 percentage. Because most of the requests gets fulfilled locally and can avoid the transfer over expensive WAN. This saves money if the host charges for the traffic.

Web Caching

A web Cache lies between one or more web servers and clients, which analyzes the requests comes, save copies (HTML, images and files) and waits for another request for the same and responds with the saved copies instead of asking for the original to server it again. While Caching used to store Database information, retrieving the information from database takes time. With careful optimization we can reduce the time and lessen the burden imposed on database to a certain extent, but sure we can never eliminate it. In the case of page caching, cache server monitors which page object are frequently requested and store those objects locally. When these objects are later requested, the cache delivers it from local storage rather than forwarding the requests on to the original server.

Web Caching can mainly divided into

• Web content Caching (Output Caching)
• Data Caching
