LinkScan 6.0 has increased speed with less memory

San Jose, CA, October 12, 1999. Electronic Software Publishing Corporation (Elsop) introduces LinkScan version 6.0.

"The dynamic nature of the World Wide Web means that hyperlinks can become outdated rapidly as sites relocate to different servers and, as structure and content are updated. Experience has shown that as many as 20 percent of hyperlinks can become outdated in just a few months. Even maintaining the integrity of the links within a given site can be a problem, especially if more than one person is involved in updating the pages, " said Kenneth Churilla, president and co-founder of Electronic Software Publishing.

"Webmasters concerned with the quality of their site should revalidate all hyperlinks on a regular basis; at least weekly and whenever changes are made to content. Manual testing of that intensity is essential to maintain quality, but prohibitively time consuming and expensive. LinkScan solves the problem by automating the task," explained Malcolm Hoar, chairman and co-founder of the company.

LinkScan is the industrial strength link checking and website management tool for Unix, Linux, Windows 98 and Windows NT operating systems. It is the most accurate, fastest and most scaleable product available and it is highly customizable. It also does HTML validation. LinkScan creates two types of publication quality SiteMaps and it is professionally supported. LinkScan 6.0 includes some significant enhancements to the scanning modules.

Enhancements to the Windows version of LinkScan include the following. Web sites are now scanned via multi-tasking HTTP navigation and multi-tasking validation of external links is also supported. Users can specify the number of slave processes to be used in the scan in the graphical windows interface. The time-out/retry logic has been greatly improved when checking slow or hung links. These changes eliminate prior restrictions due to limitations of the Perl implementation for Windows and greatly improves performance.

Enhancements to the Unix version of LinkScan include the following. Web sites are now scanned via multi-tasking HTTP navigation and the memory requirements are significantly reduced when validating external links with multiple processes.

These performance improvements will be quite significant for web sites that have a lot of dynamic content that must be processed with HTTP.

LinkScan checks websites through either the file system or the web server. Both processes are necessary. The file system process is ten times faster than the web server process and it enables LinkScan to identify orphan files. Checking links through the web server enables LinkScan to check active elements such as CGI's, image maps, external links and Server Side Includes. Having both capabilities also enables the user to mirror their production server on either their workstation and/or a development server.

Some of LinkScan performance features include:

  • Benchmarked at over 40,000 links checked per hour
  • Can easily check websites with 50,000 or more external links
  • Quickly tests sites with over 250,000 pages
  • Multi-threaded processing can check over 60 links concurrently
  • Unique blend of File System & HTTP navigation for link testing
  • scaleable to any size web site and multiple sites of any size
  • Support of server aliases and server redirections
  • Facility for web access via a Proxy Server
  • Analyze dynamic pages created by CGIs, ASPs, and RDBMSs
  • Smart Probing of remote links for ultra-high accuracy
  • History of problem links helps avoid over testing external links
  • Control features for reduced processing of duplicate links
  • Efficient interactive processing produces reports rapidly

    LinkScan is being used by such large and diverse organizations as Sun Microsystems, Hewlett-Packard, NEC, Silicon Graphics, the University of Cambridge (UK), the United States Department of Defense, Goethe Institut, the California Institute of Technology, StorageTek, HBO, Shell Canada, Australia's Commonwealth Department of the Environment, Rueters, iafrica.com, Computer Associates, Candle Corp., the US National Security Agency, the Massachusetts Institute of Technology, Northwest Airlines, Brown University, The Institute of Electrical and Electronics Engineers, the MITRE Corporation, the Ford Motor Company, the National Aeronautics and Space Administration (NASA), Walgreens Pharmacy, the Boeing Company, Business Week, the Swedish EPA, Molecular Simulations Inc., 3Com Corporation, the Paris Chamber of Commerce and Ericsson, Finnish National Gallery, KPMG and the White House.
