    2. Add additional Authorized CA for custom Certificate in Azure Front Door

      Actually it is possible to bring a custom certificate for custom domain name in Azure Front Door. Unfortunately, there is a restricted list of authorized CA (cf. https://docs.microsoft.com/en-us/azure/frontdoor/front-door-custom-domain-https). CA like Lets Encrypt (https://letsencrypt.org/) are not in the list. Is possible to add it ?

    3. Intermediate CNAME for custom domain on FrontDoor

      Custom domains on Front Door and App service do not work the same way.

      Custom domains on Front Door and App service do not check DNS records for custom domains in the same way.

      My usecase:
      - I have hundreds of clients with custom domains they have registered on their own (like myclient.com)
      - My clients use www.myclient.com to access our services
      - My company owns mycompany.com
      - I've asked them to add a CNAME like this: www IN CNAME client.mycompany.com
      - I've setup this record: client.mycompany.com IN CNAME mycompany.azurewebsites.net
      - We are using custom domains on App service with…

    4. Frontdooor - TLS mutual authentication - X-ARR-ClientCert

      Allow Frontdoor to inject the client certificate into request header: X-ARR-ClientCert similar to App Services.

    5. Allow adding custom hostnames before DNS CNAME is set up on Azure Front Door

      Allow adding custom hostnames before DNS CNAME is set up. That way we could prepare the Front Door configuration before setting it live on our domain. This is useful for scenarios when some transitions to Front Door (for example from Traffic Manager) with a domain which is already in use in production.

    6. Increase limit of custom domains per front door

      There is a limit of 100 custom domains per front door.
      This works well for apps that only require only a handful of domains, but SaaS applications often require it's customers to be on their own domain. This limitation currently prevents SaaS platforms using Azure FrontDoor.

      Alternative platforms such as Cloudflare or AWS Cloudfront already support a very large number of custom domains.

    7. Front Door Managed SSL for Apex Domain

      While you can add an apex domain by changing your name servers to Azure DNS and utilizing an alias record (similar to traffic manager), front door does not allow for "Front Door Managed" SSLs for the apex domain. As this will be one of the most required SSLs (since it's very rare for a company not to redirect the apex to www.***.com or vice versa), it would be very useful to not have to purchase a cert for this purpose since free managed SSL is a very big selling point for Front Door. Please add this, otherwise almost all customer…

    8. Add option to detach specific files from the Azure Front Door dynamic cache

      When you host a SPA (Single Page Application) on an Azure Blob storage with Azure Front Door (with dynamic caching activated):

      Everytime you release a new version of the app, users have to force-reload the page in order to get the new version.
      Because the links to the new assets (like main.***.js, ...) are located in the index.html, which has been cached.

      I was able to solve it:
      1. Let the Azure CLI set the Cache-Control header to "no-cache" on the index.html after pushing it to the blob storage:
      az storage blob update --account-name $(storageAccount) --container $web --name index.html --content-cache-control…

    9. Custom error pages for Azure Frontdoor

      Allow us to configure custom error pages in Frontdoor. Ie, whenever I deploy my app, there's a momentary blip on the restart where Frontdoor displays a generic "Our services aren't available now". It would be nice to be able to configure this - either a custom message or fully link over to a static page in a storage account.

    10. Set headers detailing TLS handshake

      Additional x-azure-{x} headers which provide details about the TLS handshake between the client and front door, such as the selected cipher, TLS version and key length. This will help provide operational insight about the client base.

    11. Allow SSL/TLS configuration on Azure Frontdoor

      Allow option to configure SSL protocols and best practices, same as an application gateway on Azure front door service.
      Currently, Azure Frontdoor supports TLS 1.0 as well, there should be an option to select protocols as well as the cipher suite.

    12. Azure Front Door to support certificates from SwissSign CA

      We use SwissSign as our certificate vendor. These certificates are trusted by most devices and operating systems, incuding Windows 10 and Azure Application Gateway.

      When it comes to Azure Front Door they don't seem to be trusted.

      For us to be able to buy/use the Azure Front Door service we need for it to support our certificates that we use on our backend servers.

    13. Challenges in making AFD Work as a CDN for on prem resources

      We would like to use the AFD's WAFs capability and CDN for protecting our on premise farm

      We will need to create the service on AFD and have Backend access via an IP and Backend header
      Conceptually and by design the service should be able to do it
      Challenges:

      0. On a single IP we have many Names that are published in HTTPS only, a single certificate with SAN entry for all the names
      The IP address normally does not respond to any request and give a 403

      We have modified the IP to respond with 200 for HTTP
      but…

    14. Provide ability to enforce baseline rules across Azure tenant for Azure Front Door WAF

      Providing the ability to define a baseline set of rules for Azure Front Door WAF will help enterprise security teams keep a consistent security posture for endpoints no matter who owns the deployment of the Azure Front Door instance. Ideally this could be configured to enforce this baseline across all Azure Front Door instances within an Azure tenant.

    15. Front Door: TM’s FQDN is reflecting in drop down menu mutiple times when adding app services to a front door backend pool

      Currently if i have multiple app services connected to a traffic manager and i want to have a Azure Front door, TM's FQDN reflects in the dropdown while adding these appservices in Front door backend pool.

      For eg. Say xyz.azurewesites.net and pqr.azurewebsites.net are connected to tm.trafficmanager.net. When I create a front door and try to add these appservices to the pool, tm.trafficmanager.net shows up two times instead of real appservice names.

      This is a issue where if I want add app services among multiple backend pools say one for read and one for write, there would be no way to…

    16. HTTP -> HTTPS redirect routing shouldn't count in the price

      The current pricing of Azure Front door service is $0.03 per hour per routing rule (~27$ per month per routing rule). Adding a rule for simple HTTP -> HTTPS redirect immediately increases the cost by $27 per month.
      Who am I to suggest prices, but I think it would be nice if a simple HTTP -> HTTPS redirect didn't count in pricing.

    17. Azure Front Door should automatically configure custom domains on backend app services

      When a custom domain is registered with Azure Front Door it should register that custom domain with backend app services.

      When backend app services do not have the same custom domain as AFD, app service session cookies are not passed back to the browser. Therefore session affinity is broken.

      Although there is a workaround that involves pointing the custom domain at the app services to register the domain, then pointing the custom domain back to AFD, it some cases that's just not feasible.

      We will be halting further rollout of AFD to our customers until this issue is resolved.

    20. Enable Azure Front Door managed certificates in ARM Templates

      Azure Front Door is GA. We really want to use it throughout our build/release cycles. We are not able to do so because it is not possible to setup the custom domain AFD managed certs via ARM templates. When will this be available.
