  1. Provide API to access CDN Supplemental Management Portal

    API is needed to add new rules (e.g. Country Filtering, Token Auth, etc.) for newly added content.

    Use case: User adds new video content in CMS where he is able to block this video in some regions.

    • Signed cookie in CDN

      Enable authenticated access to CDN without the need to change URL or headers. This is especially useful for referencing a static web page in an IFRAME.

      Scenario. When user signs in to example.com, we would first redirect users to a non-cached page on CDN cdn.com, which would set the signed cookies, before redirecting back to example.com.

      On example.com, we have an IFRAME that references a static webpage on cdn.com. The static webpage references other images, JavaScript and CSS on cdn.com. The access to the webpage and other resources are authenticated by the signed cookie.

      AWS implementation http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/private-content-signed-cookies.html

        • Correctly handle CORS with Range header

          When browser sends a Range request to CDN, CDN downloads the entire file from origin, then serve the appropriate range to the browser. However, when serving the content range, it does not send the CORS header that is present in the origin, thus breaking cross origin requests.

                              • Provide a way to Supress ETags when Using Akamai CDN and Blob Storage

                                When using the Akamai CDN to serve content from Blob storage (strong) ETags are sent back with the response. These seem to confuse clients and make response time slower than they could be.

                                e.g. https://jsfiddle.net/29zozLjk/show/ in Chrome this resource returns a 304, whereas it should always load from cache

                                It would be nice if there was a way to prevent these ETags being applied - either at Content Storage or the CDN.

                                  • Allow different CDN cache and client cache times for Azure CDN Standard

                                    Currently the only option is to set the Max-Age header on the content which sets the TTL on the CDN endpoints AND on the clients.

                                    If we use the Purge API to refresh the CDN content, the clients still have the cached version.

                                    Akamai has a "downstream-ttl" attribute on the Edge-control header that allows for client expiration customization while letting the "max-age" header set the CDN expiration.

                                    This way you can set the downstream-ttl to 0 (client always requests to CDN) while CDN can cache the original content until Purged.

                                    Without this, the Purge command is not entirely useful.

                                    • There seems to be a issue when enabling compression when using Akamai

                                      It seems when using Akamai as the CDN and compression is enabled, static content which isn't compressed (e.g. images) always returns a pragma: no-cache header.

                                      Either this is a bug, or an undocumented 'feature' .

                                      • CDN Forward HTTP Proxy

                                        Currently we are only serving static content through CDN, it would be nice to serve dynamic content with cookies etc, where CDN kind of acts as a Forward HTTP Proxy instead of CDN. Benefit will be of multiplexing HTTP traffic to single host.

                                          We need more details on what you are looking for regarding “multiplexing HTTP traffic to a single host” The CDN is built as a reverse proxy and can be used for both static and dynamic content. For dynamic content that you don’t want to be cached by the CDN you can either set the appropriate cache control header (e.g. max-age) or use the bypass cache capability in the rules engine in the Azure CDN Premium to control this for specific content. Long term we are working on enabling this capability also in Azure CDN Standard.

                                        • Provide Feedback as to if CDN can reach origin url.

                                          Right now you need to wait 90 minutes or so (potentially) if you are getting 404 errors on content. It would be nice to have some kind of visual feedback on the endpoint configuration page if the origin url was reachable from Azure.

                                            With Azure CDN from Verizon it takes up to 90 minutes for configuration for a new CDN endpoint to propagate to all worldwide CDN POPs. For a new endpoint you will get back 404 errors until the configuration has propagated to the CDN POP that you are making requests to. We are working with Verizon to reduce this propagation time and also working with them so that we can deterministically provide feedback via API and UI when this propagation has completed.
                                            With Azure CDN from Akamai CDN endpoints are typically created in under a minute and the status of via API and UI accurately reflects when endpoint configuration has completed.
