How can I solve this problem, if it is possible to use another method the download pages from internet or when the program is choked, if it is possible to stop it and restart the program again?

'content', not 'Content'.

Since others have addressed your main question, I will only add:

- Don't use TAB characters to indent code in Usenet posts.
- Follow the naming conventions. You were told this in another thread. Why do 
you continue to flout them?
- Don't ignore exceptions! (Yes, you were told that before. I'm repeating it.)
- Except for specialized use cases, of which this isn't one, don't catch 
'Exception'. Use specific exception types.
- Don't initialize variables to values you won't use.
- Don't declare a method to throw an exception that it cannot possibly throw.

And your program isn't "choking", it's waiting for input.
