WebClient - problem reading from web page

Question

Hi,

 

I build winform which try to read data/string from webpage.

 

In the following code I get no string in variable reply. however if I am using the comment url ("http://www.finviz.com/") I get string in the reply.

 

Can you help to see why I am not getting data in this code?

 

Thanks

 //url = "http://www.finviz.com/"; // This is working
