Try this

using System;
using System.Net;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string fileLocation = @"<YOUR URL>";
var serverResponse = GetServerResponse(fileLocation);
Console.WriteLine("URL Validity : {0} \n Server Response : {1}", serverResponse.Item1, serverResponse.Item2);
Console.ReadKey();
}

private static Tuple<bool,string> GetServerResponse(string fileLocation)
{
bool isValidURL = true;
string data = string.Empty;
using (WebClient client = new WebClient())
{
try
{
data = client.DownloadString(fileLocation);
}catch(WebException weX){
isValidURL = !isValidURL;
data = weX.Message;
}
}
return Tuple.Create<bool, string>(isValidURL, data);
}
}
}


Case 1: When Success
URL Validity : True
Server Response : This is a sample test


Case 2: When Failure(Wrong URL)

URL Validity : False
Server Response : The remote name could not be resolved: xyz.cloudapp.net'


Hope that helps.

You need to use Server.MapPath() - this function converts the virtual path to physical path.

In the web.config FromLocation value should not be "http://...." but it should be from the root of the application. Like

<add key="FromLocation" value="/" >
root of the application

string urlPath = Server.MapPath(urlPath);
string fileLocation=urlPath + @"\SampleText\sample.txt;

Now this should recognise the file location.

Thanks
