          • Provide access control feature

            I'm looking to use Azure CDN to replace a password-protected FTP area. The lack of access control is preventing me using the CDN.

            • Alerts triggered from a URL RegEx

              It would be great if we could register alerts to trigger from a URL hit or number of hits / second.

                      • 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.

                                  • Provide Access to CDN Storage

                                    Currently there seems to be no way to access the storage the CDN is using.

                                    I would like to use Function App with a NodeJS Blob Trigger to minify any CSS and JS files that land up on the CDN Storage.

                                    Another scenario is to jslint & css lint any js and css files that gets stored in CDN storage and send notifications if there's anything that won't lint.

                                    Yet another scenario is to use a blob trigger blobs and optimize any images that gets stored.

                                      There currently isn’t any way to access storage that is used by the CDN for caching purposes. Content is never permanently stored in the CDN cache. By default content is stored for a max of 7 days. Longer or shorter times for this TTL can also be specified. However, in all cases this is just a max value and content can be removed from the CDN’s cache if it isn’t being actively accessed.

                                      Long term we are investigating the ability to have the CDN automatically optimized images and reduce the size of content (e.g. minify files) before they are delivered to clients.

                                    • Support WebApp deployment slots for Endpoints

                                      In the Azure Portal, when configuring an Endpoint for a CDN resource, you can select WebApp. It gives you a nice list of WebApps you have access too. The problem is, if those WebApps are using Deployment Slots for staging (Dev, Test, Prod); you can't add an Endpoint for anything other than the production slot.

                                      We would like to have a mirrored setup where our WebApp Dev slot is accessible through the CDN.

                                      The work around is to add a custom origin, which works--but seems like the WebApp feature could be more robust.

                                      Thanks!

                                      • CDN image auto image crop and resizer functionality for images

                                        It would be really good, if the CDN could handle query strings and for the file format of images, handle resizing and cropping parameters automatically to resize our content needs... This done by the Azure CDN by its own.

                                        • Prevent Azure CDN Bandwidth abuse

                                          Hello,
                                          I have already made a couple of posts in regards to this issue on StackOverflow: http://stackoverflow.com/questions/35488753/how-to-prevent-azure-cdn-bandwidth-abuse-by-malicious-bandwidth-vampire-requests and on MSDN CDN forum: https://social.msdn.microsoft.com/Forums/azure/en-US/9e37ca24-b38d-4193-847b-f679eab76aa5/azure-cdn-bandwidth-abuse-by-malicious-bandwidth-vampire-requests?forum=azurecdn but so far, unfortunately, no good solutions to the problem were offered. So I thought it would be a good idea to post this idea here as well, and get a little more into detail on how to solve the issue since this little fix can easily be integrated into the upcoming WAF offering with the Premium SKU.

                                          Problem:
                                          To summarize, the problem can simply be stated as follows: Any large multimedia content file such as an…
