Check for updates

• Mark Davis Check for updates Nov 07 2003, 08:13
  I'm trying to figure out how to tell if a site has been updated, I have
  already tried many ways and they have failed, maybe one of you smart
  people will have a solution.
  
  I tried downloading the HTML and comparing it later, this didn't work
  because most sites use PHP now and the HTML is different each time.
  
  I looked into lastModified stuff but it seems that it only works on a
  few sites and only HTML pages?
  
  So does anyone know how I can figure out if a site has been updated?

  If you don't consider "the HTML is different each time" an update,
  how do you define an update?  If you can answer that, you'll
  have most of the problem solved.
