I'll explain my question with an example.
Suggest I go the the url:
http://www.google.co.il/#q=university
and then I right click and choose view source, I don't get the real html source,
I'm sure of that because if I search in the code unique words that appear in the document I get no results.
I know that in chrome I can mark something and check the component, then I can see the real source code, but I want to use a java program for getting the code so I want to understand the issue of why I don't see the real html source when I go to 'view source'.
