Custom Content-Type header in Custom HTTP (TCP)

With a small trick

var dev=IR.GetDevice("AV & Custom Systems (HTTP)");
var headr="TestAgent" + String.fromCharCode(13) + String.fromCharCode(10) + "Content-Type: text/xml; charset=utf-8";
dev.SetParameters({UserAgent: headr});

or

Hm. Does it mean that AV & Custom HTTP driver doesn't send Content-Type header in POST request?

no, this trick only for GET

    GET / HTTP/1.1\r\n
    Host: 192.168.0.1\r\n
    Connection: Keep-Alive\r\n
    User-Agent: TestAgent\r\n
    Content-Type: text/xml; charset=utf-8\r\n
    Accept: */*\r\n
    \r\n

    POST / HTTP/1.1\r\n
    Host: 192.168.0.1\r\n
    Content-Length: 2\r\n
    Connection: Keep-Alive\r\n
    Keep-Alive: timeout=15, max=300\r\n
    User-Agent: TestAgent\r\n
    Content-Type: text/xml; charset=utf-8\r\n
    Accept: */*\r\n
    Content-Type: application/x-www-form-urlencoded\r\n
    \r\n
