OSS Upgrade Notice
Upgrade Time: 00:00:00 (UTC+8) September 23, 2019
Content: For all buckets created on and after September 23, 2019, 'Content-Disposition:'attachment=filename' will be automatically added to the response header when you access image files through OSS domain names over the Internet. The image files will be downloaded as attachments. Image files of these MIME types (image/jpeg, image/gif, image/tiff, image/png, image/webp, image/svg+xml, image/bmp, image/x-ms-bmp , image/x-cmu-raster, image/exr, image/x-icon, image/heic) and extensions(jpg, jpeg, jpe, png, tif, tiff, gif, svg, bmp, ico, ras, dib, svgz, webp, bm, jfif, x-png, exr and heic) will be affected.
This upgrade does not affect image files accessed through custom domain names. For more information about how to use a custom domain name to access OSS, see 'Bind a custom domain' ' in OSS documentation.
Note: Buckets created before 00:00:00(UTC+8) September 23, 2019 are not affected by this upgrade.
