curl: catching exception on connect.

[Suliman via Digitalmars-d-learn]

I can't understand why I am getting exception on next code:

	void downloadFile()
	{
		foreach(link; links)
		{
			try
			{
				writeln(connect(link));
			}

			catch(Exception msg)
			{
				writeln(msg);
			}
		}
	}
	
Exception text:

By the code App should simply write the server response like 400
or 200. But it's simply crash.

It's look like I do not right understand exception level and way
of use them. Could anybody help me?
