The WWW is very dynamic in nature and is basically used for the exchange of information or data, the content of web page is added, changed or deleted continuously, which makes Web crawlers very challenging to keep refresh the page with the current version. The web page is frequently changes its content hence it becomes essential to develop an effective system which could detect these types of changes efficiently in the lowest browsing time to achieve this changes. In this chapter we compare the old web page hash value with the new web page hash value if hash value is changed that means web page content changed. The changes in web page can be detected by calculating the hash value which is unique.
