hi,

i don't know if it works on HTML5 target of OpenFl because i tried everything to run the below snippet , but i am always getting :

POST http://localhost:4000/ 500 (Internal Server Error)

AsyncHttp.hx:188: thNPv5ks INFO: Response HTTP Status 500
AsyncHttp.hx:197: thNPv5ks ERROR: Request failed -> Http Error #500
Tests.hx:120: ERROR 500 Internal Server Error)

Request Headers
POST / HTTP/1.1

i don't know what is the problem but now i have to use OpenFL URLLoader which is working as expected
but this one was the best thing i hope you will get some time to fix this precious library thanks.

              var request = new HttpRequest
		({
			url : "http://localhost:4000/",

			callback : onResponse,
			//callbackError : onCallbackEror,
			//callbackProgress : onCallbackProgress,

			method : HttpMethod.POST,

			//headers : _headers,

			timeout : 10,
			async : true,
			http11 : true,

			content : Json.stringify('{"query":"{\n  feed {\n    title\n\t\ttext\n  }\n}\n"}'),
			contentType : "application/json" 

		}); //end HttpRequest instance

		var fingerprint:String =  request.fingerprint;
		trace("fingerprint: "+fingerprint);

		request.timeout = 20; // example to set the timeout to 20 seconds
		request.send(); // start the request as set
