    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 ?

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

    4. 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…

    5. 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.

    6. Azure Front Door support for self-signed certificates on backend origins

      It would be great to be able to use self-signed certificates on the backend pool VM's, Cloud Services, etc, but continue to use a Public CA signed certificate for the Frontend host.

      Especially for Dev/Test environments where the default *.azurefd.net front-end domain/certificate is suitable for testing purposes and traffic to the back-end pool should be across https. It would save needing to buy and install certificates for dev/test environments.
      Or, perhaps long-life "origin certs" could be issued by Front Door to be used on the back-end pool. Similar to Cloudflare's Origin Certs concept where the issued certs are trusted by…

    7. 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.

    8. 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.

    9. 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…

    10. Support rewriting HTTP headers

      In order to have more control over accessing multiple services through one facade provided by Front Door it'd be nice to have an opportunity to rewrite/add some HTTP headers when it's needed. Using rewriting it'd be possible to protect apps by creating some checks on added header value (e.g. 'x-frontdoor-key') on the app side. It'd make possible to be sure that all request are coming through WAF

    12. Azure Front Door - cache Key Vault sourced certificates

      We use Front Door to host multiple clients under the same domain, and configured HTTPS with a wildcard certificate sourced from Azure Key Vault. The same source Key Vault, secret name and secret version is used for all frontend endpoints configured.
      Customer DNS records:
      customer1.domain.com -> frontdoorname.azurefd.net
      customer2.domain.com -> frontdoorname.azurefd.net
      customer3.domain.com -> frontdoorname.azurefd.net

      Wildcard certificate in Key Vault *.domain.com

      Every time a new client front end is added and HTTPS configured for it, the certificate is deployed again, which takes 20 minutes. Front Door should recognize that the same version of the same certificate is already been uploaded before and…

    13. 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.

    14. 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.

    15. 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…

    16. Allow RegEx Search Patterns for URL Path Patterns in Front Door Rules, and Multiple Wildcards

      Right now, Azure Front Door URL Path Patterns support matching through only one wildcard (asterisk)
      that currently must be preceded by a slash and must appear at the very end of the URL Path Pattern.
      This is still true as of September 1, 2019.

      For some use cases, it is crucial to have much more control over each URL path pattern, than the current existing functionality in Azure Front Door.

      We would like to see the possibility to have more versatile rules in Azure Front Door, including both of the following:

      1) The ability to place more than one wildcard…

    17. 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.

    20. Support to disable health check of Frond Door

      The health check of Frond Door is too frequent, which leads some negative impact. For example:
      1. More user pages, consume a lot of computing resources.
      2. If we use Azure DNS zone, DNS query will take extra charge.

      Sometimes we only have one backend VM as backend pool, which health check is not required.

      It would be highly suggested to have a feature like users can disable health check manually in case it's not needed.

      Thanks!
