server keeps returning 404 not found

Oct 09 '16 at 18:21

Chilkat Mono 9.5.0.59 on Mac and Windows, I am sending a post request to this address: http://wms.qgiscloud.com/guillaume_av/tetst1?

POST param:

My code:

Http httP = new Http();
http.PreferIpv6 = true;
if(credentials != null)
{
http.Login = credentials.UserName;
http.Password = credentials.Password;
http.BasicAuth = true;
}
http.UseBgThread = true;
http.PBinary("POST", Url, Encoding.UTF8.GetBytes(parameters), "application/xml", false, false);

It succeeds in my browser but returns the following eror with chilkat:

Any help appreciated Guillaume

This URL: http://wms.qgiscloud.com/guillaume_av/tetst1? is a bit strange because it has a "?" at the very end, but with no query parameters.

If I copy-and-paste just that URL into a browser, I get an error (but not a 404 not found). I know it's a GET and not a POST when I do that, but I'm just experimenting..

If I remove the "?" from the end of the URL, and paste "http://wms.qgiscloud.com/guillaume_av/tetst1", then I get a 404 not found. But this is a URL where the final part in the path is assumed to be a file (not a directory).

If instead add a "/", and paste "http://wms.qgiscloud.com/guillaume_av/tetst1/" in a browser, then this returns the same as for "http://wms.qgiscloud.com/guillaume_av/tetst1?".

Chilkat is likely discarding the "?" because there are no query params. Instead, use "http://wms.qgiscloud.com/guillaume_av/tetst1/". See if that solves the problem.
