setHttpHeader overwrites the header instead of adding new one

[oskarsh]

Hey,
I am looking into some networking with HISE and found a bug regarding the headers. Server.setHttpHeader does not add a header but instead overwrites the last one resulting on only one header being sent.

In this example:

Server.setHttpHeader("Content-Type: application/json");
Server.setHttpHeader("Header1: I am header 1 and get overwritten");
Server.setHttpHeader("Header2: I am header 2 ");

only the last Header2 is being sent to the Server instead of all 3.

I've set up a python testing server that prints out the header and the payload you can easily run it locally with $python3 debugHeaders.py .

--> Python Debug Server Gist

This exposes a route called /test/ which I call in my snippet:

That's intentional (so that you can use different headers for subsequent calls), just put all three into a single string with new line characters.

@Christoph-Hart Thanks for letting me know!

@Christoph-Hart I've looked further into the Server component and it seems like HISE always adds a trailing slash at the end of the route. So

Server.callWithPOST('localhost:4000/test', p, function(status, reponse){});

actually calls the /test/ route and not the /test one which ends up in a 404.

Is there a trick to not add a trailing slash in hise?
