Cached HTML compresses extremely well, but the drop-in currently serves raw bytes via readfile(), leaving compression to the web server (or none).

Spec:

  • On cache write, also store a gzencoded sibling (index.html.gz or index-gzip.html)
  • On serve (drop-in + in-WP path), when the client sends Accept-Encoding: gzip, serve the compressed variant with Content-Encoding: gzip and correct Vary header
  • If rewrite-rule static serving (#11) lands, express this via standard MultiViews/mod_rewrite gzip rules instead
