 https://github.com/torproject/tor/blob/8020d6fb05d9477e77c6ca554dc1288873f6115c/src/feature/dircache/dircache.c#L1293

 I verified that there's not Content-Length in the header doing that.

 If i call detect_compression_method, as
 test_dir_handle_get_status_vote_current_consensus_ns is doing:
 https://github.com/torproject/tor/blob/8020d6fb05d9477e77c6ca554dc1288873f6115c/src/test/test_dir_handle_get.c#L1875,
 it will say the compression method is UNKNOWN_METHOD, instead of
 ZLIB_METHOD. What i'm doing wroing?
