So, I'm trying to write a web spider for some data gathering from a
public database webserver. Anyway, in response to a POST, the webserver
returns "200 Script Results Follow" instead of "201 CREATED". While
both IE and Firefox ignore the odd header, this response kills my
HttpWebRequest with a WebException - "System.Net.Web Exception: The
server committed a protocol violation. Section=Respons eStatusLine".
Does anyone know of a workaround for this?
Thanks,
Colin

A 201 should only be returned if a new resource was created on the
server-side. If that is the case but you get a 200 response instead,
it's a server-side error.
Do note that "200 Script Results Follow" is a perfectly legal HTTP
status line. The HTTP spec defines status codes, but only *recommends*
reason phrases. Accordingly, "Script Results Follow" is as good as "OK"
or "Aye aye, Sir".
While both IE and Firefox ignore the odd header, this response kills my HttpWebRequest with a WebException - "System.Net.Web Exception: The server committed a protocol violation. Section=Respons eStatusLine".
Does anyone know of a workaround for this?
What .NET version are you using? I've tested this briefly in both 1.1
and 2.0 Beta 2, and both work with arbitrary reason phrases:

I have some issues with HTTP Headers and I was hoping for
some pointers or references to good articles.
Here is the problem.
I have 6 .aspx pages, each page contains a common .ascx.
This ascx serves two purposes, 1. it contains a tab strip
with response.redirects to navigate to the other pages;
2. I authenticate the user by check to see if a cookie
exists, if it doesn't I redirect to a login screen.
