- Fix static responder so it doesn't replace its own headers config, and instead replaces the actual response header values - caddyhttp.ResponseRecorder type optionally buffers response - Add interface guards to ensure regexp matchers get provisioned - Use default HTTP port if one is not explicitly set - Encode middleware writes status code 200 if not written upstream - Templates and markdown only try to execute on text responses - Static file server sets Content-Type based on file extension only (this whole thing -- MIME sniffing, etc -- needs more configurability)
