posted July 8, 2004 6:12 AM Hello, I'm having a problem with Web Tool. I try to access a web page which is protected with basic authentification. I'm using : HTTP1.Get strResultat, , strUser, strPassword It works perfectly at home, with or without a proxy. At the customer, however, it doesn't work. What he receives is a "401 error authorization required" from apache. When he tries to access the page with Internet Explorer, the authentification works fine. He is behind an ISA proxy (which I can't install at home). I don't have a clue what it is due to. Do you have an idea ? Thank you in advance. Regards, Guillaume Dhion ImmoStore. |

posted July 8, 2004 9:16 AM Can you get a sniffer on the customers computer? The easiest solution would be to trace an IE session and compare it to a trace of your program. If you can't do that, I would suggest getting the same proxy he has and running some tests at your site. |

posted July 9, 2004 5:02 AM Thank you for your answer. I've done some tests at the customer site with Ethereal. I've extracted what I think is important from the trace. I can send you the complete Ethereal files if you want.

[End] I think the problem comes from the fact that your tool doesn't send another request with Basic Authentification credentials after having received the 401 error page (though it does in my company just like IE does at the customer site). Can you please help me ? Thank you. Guillaume Dhion ImmoStore. |

posted June 23, 2005 12:45 PM This is an old post, but I'm having a similar problem when trying to use a Get statement. This is the code I'm using (in VB6): objHttps.URL = objHttps.UrlScheme & "://" & objHttps.UrlRemoteHost & objHttps.UrlPath & sMask objHttps.Head objResponse, msLogonID, msLogonPswd objRequest.Add ("Authorization: Basic QU5QQUNfSFRUUFM6V3F0WjZ2Mzc=") objHttps.GetEx objRequest, sContent, objResponse, msLogonID, msLogonPswd This is what I get back with a packet sniffer: 11:39:08.250 HEAD /AgentFTP/Auth/a0001.txt HTTP/1.1 165 0xE88 0x34C 13369356 <IP Address> Accept: */* User-Agent: Dart Communications PowerTCP Host: secure.web.info Content-Length: 0 Connection: Keep-Alive 11:39:09.328 HTTP/1.1 401 Unauthorized 255 0xE88 0x34C 13369356 192.168.220.18:443 Content-Length: 1539 Content-Type: Text Document Server: Microsoft-IIS/6.0 WWW-Authenticate: Negotiate WWW-Authenticate: NTLM MicrosoftOfficeWebServer: 5.0_Pub X-Powered-By: ASP.NET Date: Thu, 23 Jun 2005 16:39:10 GMT 11:39:09.562 GET /AgentFTP/Auth/a0001.txt HTTP/1.1 145 0xE88 0x2C0 13369356 192.168.220.18:443 Accept: */* User-Agent: Dart Communications PowerTCP Host: secure.web.info Connection: Keep-Alive 11:39:09.625 HTTP/1.1 401 Unauthorized 255 0xE88 0x2C0 13369356 192.168.220.18:443 Content-Length: 1539 Content-Type: Text Document Server: Microsoft-IIS/6.0 WWW-Authenticate: Negotiate WWW-Authenticate: NTLM MicrosoftOfficeWebServer: 5.0_Pub X-Powered-By: ASP.NET Date: Thu, 23 Jun 2005 16:39:10 GMT |

posted June 23, 2005 1:01 PM The same answer as above still applies. The issue would be too complex to debug on the forum so you should contact support@dart.com to discuss the other options. |
