How to use OSS gzip?

OSS gzips the static contents of common webpages (HTML, Javascript, XML, and JSON) by adding Accept-Encoding to the header of the Get request, but the following conditions must be met:

• File size must be equal to or greater than 1 KB.
• Content-Type must be text/cache-manifest, text/xml, text/plain, text/css, application/javascript, application/x-javascript, application/rss+xml, application/json, or text/json.
