This works when I paste it into my IE browser. You shoudl get an error complaining about the username or password. This is OK. At least it is reaching the server. However, it does not work when I call it from SAP. I've called many other API calls using the same code and they all work fine. Not sure what is different about this call. Here is the error I get from SAP:

400 Bad HTTP request. Illegal request version

Has anyone run into this?

The Web server (running the Web site) thinks that the data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) was 'malformed' i.e. did not respect the HTTP protocol completely. So the Web server was unable to understand the request and process it.

It almost always means bad programming of the client system and/or the Web server.

Do you know what "Illegal Request Version" means? Is this HTTP 1.0/1.1/2.0?
