I am using a WebRequest to check if a web page or media (image) exist. On GetResponse i get a System.Net.WebException exception. I ran through 100 links and it feels like its going slower then it should. Is there a way to not get this exception or handle this more gracefully?
static public bool CheckExist(string url) { HttpWebRequest wreq = null; HttpWebResponse wresp = null; bool ret = false; try { wreq = (HttpWebRequest)WebRequest.Create(url); wreq.KeepAlive = true; wresp = (HttpWebResponse)wreq.GetResponse(); ret = true; } catch (System.Net.WebException) { } finally { if (wresp != null) wresp.Close(); } return ret; }
Try setting
after the ‘KeepAlive’ line. If the webserver you are calling is smart enough, that will tell it not to return any body contents which should save some time.
