Question

I need to check if a text file exists on a site on a different domain. The URL could be:

http://sub.somedomain.com/blah/atextfile.txt

I need to do this from code behind. I am trying to use the HttpWebRequest object, but not sure how to do it.

EDIT: I am looking for a light weight way of doing this as I’ll be executing this logic every few seconds

Answer 1

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(
                       "http://sub.somedomain.com/blah/atextfile.txt");

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

if (response.StatusCode == HttpStatusCode.OK)
{
    // FILE EXISTS!
}
response.Close();
