I have a code that connects to a php page to check a version, but its always so slow on the first time.
After that it gets the content instantly, anyone know why?

I use:

C#

try
            {
                WebRequest req = WebRequest.Create(URI);
                WebResponse resp = req.GetResponse();
                StreamReader sr = new StreamReader(resp.GetResponseStream());
                return sr.ReadToEnd().Trim();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
                return null;
            }

Possibly a caching issue.

I'm still very new to this, how do i get a string of a WebResponse?

You are using a webresponse, and reading it into a StreamReader from a Stream. Calling readtoend() on the StreamReader is returning a string.

You are doing that in these 3 lines of code:
WebResponse resp = req.GetResponse();
StreamReader sr = new StreamReader(resp.GetResponseStream());
return sr.ReadToEnd().Trim();

I got it to work, but it's the same speed, any other things?
