Where does this value get set at?

I'm reading through the code, looking to understand things, and I don't see where this value gets set in the codebase anywhere. I'm missing something, and I'm pretty sure the value is intended to be if the Transfer-Encoding is set, but I'm not sure how it gets set for this to ever return.

I didn't put the version that I'm on because I'm just in the source code, this isn't an issue with something running anywhere, I'm just trying to learn. If it helps I've got 6.6 on my system, but literally there is no code running anywhere that I'm affected by this in any way.

function ServerResponse(req) {
  OutgoingMessage.call(this);

  if (req.method === 'HEAD') this._hasBody = false;

  this.sendDate = true;

  if (req.httpVersionMajor < 1 || req.httpVersionMinor < 1) {
    this.useChunkedEncodingByDefault = chunkExpression.test(req.headers.te);
    this.shouldKeepAlive = false;
  }
}

Specifically the req.headers.te for those looking at this in the future wondering what in the world I'm talking about. Probably should link to the latest hash instead of what I put in the actual ticket ...

node/lib/_http_server.js

Line 93 in 4e6dc00

this.useChunkedEncodingByDefault = chunkExpression.test(req.headers.te);

It refers to the TE HTTP request header, not a value that Node specifically computes.

Oh, /facepalm https://en.wikipedia.org/wiki/List_of_HTTP_header_fields

Yes yes, I see it. Sorry, thanks @cjihrig
