If you ever had to upload large volumes of data over HTTP, you probably ran into timeout issues. The default Timeout value for HttpWebRequest is 100 seconds, which means that if it takes more than that from the time you send the request headers to the time you receive the response headers, your request will fail. Obviously, if you’re uploading a large file, you need to increase that timeout… but to which value?
