important to note that the extraheaders are only useful if the receiving end knows how to handle them and are typically used for debugging or to provide additional info to developers about the request. For example, you may have a "X-powered-by: yourapp.exe/1.0.2" to know what version of your exe is on the other end.
Once again, thank you for the info. You seem to be quite knowledgeable with reference to HTML code. What I hear you saying about this particular item, is that it is not really necessary to support it. I am trying to streamline the code in advance of introducing encryption. I am not trying to implement full web server support. One of the things I had to do was receive and send data as byte values instead of string. Encrypted data uses the full ANSI values rather than ACSII.
