The World Wide Web is a huge source of hyperlinked information contained in hypertext documents. Search engines use web crawlers to collect these documents from web for the purpose of storage and indexing. However, many of these documents contain dynamic information which gets changed on daily, weekly, monthly or yearly basis and hence we need to refresh(More)

The user has to sift through scores of pages to come upon the information he/she desires. Web crawlers are the heart of search engines. <b>Mercator</b> is a scalable, extensible web crawler,(More)
Study reports that about 40&#x025; of current internet traffic and bandwidth consumption is due to the web crawlers that retrieve pages for indexing by the different search engines. As the size of the web continues to grow, searching it for useful information has become increasingly difficult. The centralized crawling techniques are unable to cope up with(More)
