plugins/compress/compress.cc:1090–1128

* This handles a compress request * 1. Reads the client request header * 2. For global plugin, get host configuration from global config * For remap plugin, get host configuration from configs populated through remap * 3. Check for Accept-Encoding header * 4. Check for Range header * 5. Schedules TS_HTTP_CACHE_LOOKUP_COMPLETE_HOOK and TS_HTTP_TXN_CLOSE_HOOK for * further processing *
