Its a regular expression. There are several web sites that 
explain how they work. The one you have is a fairly complex 
one but the principles are straightforward.

If you can, goo to informIT.com (you';ll need to register),
and do a searchh for my name and you should find an article 
on regular expressions that explains their use.

[ Or you could buy my book which contains the same info in 
  a chapter :-) ]

Not sure but the fact you used \\ instead of // after 
the http might have confused things?
