  How to determine a page change with HTMLUnit?
  
  I'm looking for a smart way to determine if a web site has changed since I last ran a check with HTMLUnit against it.
  I'm using HTMLUnit to scrape some values of a web page which fails from time to time because the page's layout has changed.
  In these cases I want to get notified that the page looks different since my last visit.
  I thought about persisting the page object that I get via HTMLUnit, by simply writing it to a file.
  Next time I run my program, I could compare the fresh object with the persisted one.
  Any opinions on this? Is there a smarter way to deal with this?
  
  A:
  
  As there seems no smarter way to deal with this, I did what I suggested in my question.
  Getting the page, persisting the source and comparing this persisted html source with the fresh one next time I run the program.
  The downside is that it doesn't work with some pages like google.com as they seem to create the page dynamically. Most other sites work though.
