Alibaba Cloud OSS Update - OSS Web File Response Header Update
Update Description: To improve security, this update adds the Content-Disposition:'attachment=filename;' parameter to the response header when certain Web page objects that are stored in OSS are accessed through OSS endpoints over the Internet. When users access these Web page objects, the objects are downloaded as attachments. Web page objects of the text/html MIME type that have the htm, html, jsp, plg, htx, or stm extensions are affected.
If you use a custom domain to access OSS, the information is not added to the response header. For more information about how to use a custom domain to access OSS, see “Bind a custom domain” in OSS Documentation.
