HTTP resource pack server

A common scenario is that you have a set of static resources that you want to server up quickly via HTTP (for example: stylesheets, WASM).

This package provides a net/http-compatible http.Handler to do so, with support for:

• compression
  • gzip
  • brotli, if you have the external compression binary available at pack time
  • does not yet support Transfer-Encoding, only Accept-Encoding/Content-Encoding
• etags
• ranges

The workflow is as follows:

• build YAML file describing files to serve
• run htpacker tool to produce a single .htpack file
• create htpack.Handler pointing at .htpack file

Only the minimal header processing necessary for correctness (Content-Length, etc.) is carried out by htpack.Handler; the handler can be combined with middleware for further processing (adding headers, http.StripPrefix, etc.).
