I'm calling a server side program from a PB 2017 desktop app and getting a different result using HTTPClient verses my WinHTTP code example.

The response text returned by HTTPClient is often short, truncating a few characters off the end. I run the same server program via WinHTTP and I get the full response text.

My question is whether this is a bug in HTTPClient or maybe there is an issue with how the server side program forms the response. The Content-Type is text/plain. The response is fairly short, under 10 characters. It contains two values separated by char(11).

I just added my test case and a Classic ASP file which will return the string. Edit the ASP file to change the number of characters.

I developed a test app which makes the same call via HTTPClient, WinHTTP, and the Msxml2.XMLHTTP OLE control.

The issue in HTTPClient occurs when the response is 4 or less characters.

I'll add a bug report.

Hi Roland;

  My suggestion would be to open a Support Ticket on this aspect and attach your WinHTTP and your HTTPClient test cases for Appeon to look at. Of course, you are always welcome to attach these test cases to this Community Post as well. Maybe we can then spot something to help and/or confirm the issue.

Regards ... Chris
