HttpWebRequest 410 Status Code - Username + Password are correctprogrammatically log onto a website. I am using the code provided in VS for the AuthenticationManager Class example ( ms-help://MS.VSCC.2003/MS.MSDNQTR.2003FEB.1033/cpref/html/frlrfSystemNetAuthenticationManagerClassTopic.htm ). I have also download and tried to use the following CsharpHttp executable in an attempt to find my problem: http://support.microsoft.com/default.aspx?scid=kb;en-us;303436 Nothing seems to want to work. It doesn't matter if I set PreAuthenticate to true, it doesn't matter if I set Keep-Alive to true, etc., etc., etc. I can log into the website through IE with my username/password, but setting the credentials just won't fly. I used to use a simple OpenUrl in VB and that has no problem. I was hoping to move up in the world, but I've already spent more than a week researching this one issue to no avail. Please help. Here's what I get back: The following authentication modules are now registered with the system: Module : System.Net.DigestClient CanPreAuthenticate : True Module : System.Net.NegotiateClient CanPreAuthenticate : True Module : System.Net.KerberosClient CanPreAuthenticate : True Module : System.Net.NtlmClient CanPreAuthenticate : True Module : Mssc.Services.Authentication.CustomBasic CanPreAuthenticate : False Headers: Date: Thu, 14 Apr 2005 21:38:52 GMT Server: Apache/1.3.26 (Unix) mod_macro/1.1.2 mod_perl/1.24 WWW-Authenticate: Basic realm="Welcome to Manheim Online" Last-Modified: Fri, 07 Feb 2003 16:27:50 GMT ETag: "5ec1c4-ee-3e43de86" Accept-Ranges: bytes Content-Length: 238 Connection: close Content-Type: text/html Authentication Failed, Unauthorized Status Code: 401 Status Description: Authorization Required Hi Noel,
It looks at first glance that you are attempting Windows Authentication? The response from the server wants BASIC authentication which is very different as the username and password are just passed in as clear text encoded in base64 to the web server. You may want to do a search on Google for HTTP headers and WWW-Authenticate to see exactly how it works in basic mode and see how you will need to send headers to the server in order to authenticate.

Thanks for your response, but accorging to MSDN: "The proxy's preauthenticate property can be set to true or false. Set it to true (as shown in the above code) to supply specific authentication credentials to cause a WWW-Authenticate HTTP header to be passed with the initial request. This stops the Web server denying access on the initial request, and performing authentication on the subsequent request." I have tried many times setting the property, with no avail. Also, the NetworkCredential constructor that I am using should be automatically setting the username and password to Base64 encoded. I certain there is something very basic that I have overlooked and I will continue to look into your suggestion to make sure I have fully understood. Please let me know if you can think of anything else.

I have managed to get things to this point: Headers: Date: Fri, 15 Apr 2005 15:35:17 GMT Server: IBM-HTTP-Server/1.0 Set-Cookie: inetmmr=97686282.44070.0000; expires=Fri, 15-Apr-2005 18:35:17 GMT; path=/,JSESSIONID=0000CJVQT3NKR5LCDI1QARKHU2A:vlpo57ja;Path=/ Accept-Ranges: bytes Content-Type: text/html;charset=ISO-8859-1 Content-Length: 12 Expires: Thu, 01 Dec 1994 16:00:00 GMT Cache-Control: no-cache="set-cookie,set-cookie2" Content-Language: en Via: 1.1 www.manheim.com X-Cache: MISS from www.manheim.com Connection: close Authentication Failed, InternalServerError Status Code: 500 Status Description: Internal Server Error Although, I am not certain as to why I am getting the 500 Error. Anyone have any ideas?? I've set the cookie container on the HttpWebRequest, however, the exception still hits on the HttpWebResponse. I have set the AllowAutoRedirect = true.

I have solved my issue. For those experiencing the same, the root of the problem resided in the lackin of HttpWebRequest.Accept: myWebRequest.Accept = @"image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*"; Thanks to everyone who so kindly responded to my problem/issue.
