Authentication with HTTP libarary problem

What error do you get?
Are you using WebRequest.New3(...) ?
Hi Erel - Happy Xmas or whatever! I get a 401 exception thrown. No, I'm not using New3 - the Help only shows a New1 and a New2. I had assumed that I would need access to the Request headers to insert an Authorization line but they are read-only!

I have now tried New3 and get "Response.Value = Request.GetResponse" Error description: "The server committed a protocol violation. Section=ResponseHeader. Detail=CR must be followed by LF. Continue?"

The server in this case is the internal side of my router - I am practicing for a remote house monitoring system for a friend of mine. Looks like it won't work with the router - I shall have to wait for him to come up with the real server which will also have this sort of authentication.

I've seen this error before on one site.
I don't know how to explain it. Other sites (with authentication) work flawlessly.
Merry Christmas and a happy new year!
I googled for the error and I've fixed it now I know about New3. Needs this adding to the dbasic.exe.config (while debugging) and the exe.config of the final app. Can I suggest you do this on the next release!

    <httpWebRequest useUnsafeHeaderParsing="true" />
.NET is very (too) strict on parsing headers by default - this relaxes it.

Erel - idiot level questions I'm afraid!

I presume I need to "New3" the WebRequest object on every call to an authenticated server rather then "New1"s after the first. Does "KeepAlive" have any significance here?

I presume I also need to perform a "New1" and "Close" pair on the WebResponse for every call as well.

Thanks for the help so far.
