Add support for HEAD type request

[Tai-1120]

Hello,

I noticed in your new Game Data API for Auction House that a request for AH Data returns full AH dump + some meaningful info in the headers, especially “Last-Modified”. I would like to just send a HEAD type request to get ONLY the header data which contains “Last-Modified” to see whether I even need to download or process whole Auction House data dump. Currently it doesn’t seem to be enabled.

It would be nice.
But as a “hacky” solution, you could do what Erorus suggests in this post:

Head requests for the auction API

You want to send a HEAD request to skip the response body, but you can’t do that. Instead, send a GET request which will never return a body: one that was modified since the future. You’ll always get a 304 Not Modified, and get the Last-Modified response header.
