This metabase property disables compression for requests containing an HTTP 1.0 version number. HTTP 1.0, as described in RFC 1945, provides a minimal level of support for certain types of compression. However, some confusion exists around HTTP 1.0 compression, especially with regard to proxy servers. In order to minimize the chance of inappropriately returning a compressed file to a client that cannot decompress it, you can use this metabase property to disable compression in questionable scenarios.
