Re: How do you simulate clicking on a hyperlink?

[Sanjeev Kumar Neemkar]

Hello,

   Considering URL-1 as http://www.apache.org/ and URL-2 as
http://www.apache.org/foundation/faq.html, below is the piece of code.
It is giving ResponseBody for URL-2 as the that of URL-1.

Am i missing something, please correct me.

   Requirement: URL-2 is embeded in the page of URL-1. I need to simulate
the hyper-link(URL-2) clicking in the page of URL-1 using   HTTPClient.

Please help,

Thanks in Advance,
