Null terminated string in Http request

[MSGhero]

When the raw bytes of an Http request callback include a 0x00 byte, the string which gets sent to the onData() function is terminated and the data is dropped. Ex:

var b = haxe.io.Bytes.alloc(5);
b.set(0,72); // H
b.set(1,97); // a
b.set(2,120); // x
b.set(3,0x00); // \0
b.set(4,0x101); // e
// important data

haxe.Log.trace(b.toString().length); // 3, "Hax"
haxe.Log.trace(b.toHex().length / 2); // 5+, "48 61 78 00 65 ..."

Obviously you can't do anything about \0 in strings, but the Http request callback should be worked with so it doesn't drop data. Right now it forces all data into a string, so there's nothing a user can do with the binary. flash.net.URLLoaderDataFormat gives you the option to get the raw binary instead of text for this reason among others.

Maybe have the request come in as binary data, and loop through it to form a string with each \0 dropped? Or make onData take a dynamic and output the Bytes directly.

Tested in (openfl) flash and js.
