In the ActiveX version I need to set BasicAuth = 1. I would think the .net versions are the same. This was added by Chilkat to make sure we understand that we are sending credentials in clear text.

Thanks a lot.

I see there a security gap, what should i change to this safe?

Hi Leon, this component supports many authentication models like NTLM, oAuth and Digest. I am not security expert, but this is what I a can suggest. You will need to find out what models your service provider (the place you are posting your data to) supports and adapt your code to one of them. The chilkat example code is very solid. Also make sure that the web site is running SSL/TLS (https://...).

Hi Leon,

This is a user-to-user forum, so you can't expect immediate answers (you only asked your question today - not a lot of time to expect an answer from other users who are volunteering their time).

Since you just bought the product you should still be under your 1-year support license, so you should contact Chilkat by email. See the Chilkat support statement here

I found a solution:

In the new Version i must set: http.put_BasicAuth(1);

Than it works. In the old version it is not necessary
