Check if/time Image loads ASP.net Web Application
<p>Ive looked around and havent seen anything on what I can do for my problem, so maybe someone here can help me. Basically I have an image (http://mysite.com/Sites/P/PA/25?encoding=UTF-8&amp;b=100 note there is no file extension as this served through a script) and I want to check to see if this image returns an Image, or an error code like 404 or 403. I also want to record the response time of that. I am trying to make a web application that will monitor this software that displays the image, if it returns 404 error I know its down, if the load time is greater than 10 seconds I also know it may be down or some other action needs to be performed.</p>

<p>I thought about using <code>WebRequest.Create</code> but this wont return the time it took.</p>

<p>Any have any ideas on how I could implement this?</p>
