Designing Web Crawler Based on Multi-threaded Approach For Authentication of Web Links on Internet

In the generation with the growth of communication technology and improving social requirements, this web crawler has been used extensively in the majority of search engines and research fields. In single-threaded crawlers, concurrency cannot be achieved because it is the single-threaded approach. Due to the use of Single threaded crawlers parsing takes higher time consumption. To overcome this a multi-threaded web crawler is proposed which can reduce the parsing time. An online crawler is a web bot that consistently browses the World Wide Web, generally for the aim of Web indexing. Any computer program uses these indexes, web graphs, and associated acceptable algorithmic rules to rank the pages or keep archival records of websites. Mostly the focus of the project would be to implement a multi-threaded transferer website crawler that may download multiple websites and their paths through the initial hostnames at a certain number of threads with their ranking and at a reduced time.
