When you send a GET request to Object Storage Service (OSS) to download a static object used in web pages, such as an HTML, JavaScript, XML, or JSON object, you can add the Accept-Encoding header to the GET request and set the value of this header to gzip. This way, the object is compressed in the GZIP format before being downloaded.
Prerequisites
- The object that you download is equal to or larger than 1 KB in size.
- The Content-Type header in the GET request is set to one of the following values: text/cache-manifest, text/xml, text/plain, text/css, application/javascript, application/x-javascript, application/rss+xml, application/json, or text/json.
Examples
- Sample requests
