How to check for 404 without throwing an exception?
Posted on 2006-07-18
I want to check for the availability of a file on a web server, using the .net framework. I can easily use a WebClient or WebRequest to attempt to get data from the URL, then catch the exception that is thrown if the requested file doesn't exist.
But I want to perform this check without exceptions - I don't like using exceptions to control program flow. Is there a way to get the headers back from the web server and check them myself, or to tell some framework class to just get me the data and ignore the 404 indication in the header?
