  1. Add naked domain support to App Service Managed Certificates

    Currently naked domains are not supported when creating App Service Managed Certificates. I want to be able to create a free SSL certificate on a naked/apex domain.

    Work is actively underway to add naked domain support with an automatic renewal flow to App Service Managed Certificates. There have been some snags getting the auto-renewal flow working. We understand these kinds of delays are frustrating, but rest assured the feature is being worked on and is coming in the future.

  2. Enable users to create custom error pages for 403 and 503 service unavailable messages

    Currently 503 errors (service unavailable) present a blank white page with "service unavailable" to the users which is far from professional for us. It would be far better if we could provide a custom 503 page which would include a logo etc., and some text along the lines of "We apologise for the inconvenience, we are working on it. These issues usually resolve in about five minutes. please contact support for further help if required." or something similar.... This error might be caused by Azure network issues, so away from the web app instance.

    It would also be helpful if…

  4. Enable App Service without ASE to access Storage Account with Firewall enabled

    Currently it is not possible to configure storage account firewall to accept requests from App Services without ASE. This requires App Service to enable trusted access to storage: https://docs.microsoft.com/en-us/azure/storage/common/storage-network-security#trusted-microsoft-services.

    It is great if above is possible.

  5. Support Double Wildcard Custom Domains

    For multi-tenant applications, we require the ability for Azure to support double wildcard custom domains.

    Single wildcard custom domains are currently well supported, i.e.

    *.mydomain.com

    catches all unmapped, single subdomain urls e.g. level1ex.mydomain.com, level2ex.mydomain.com etc

    The issue (which isn't documented: see forum post below) is that secondary level wildcards are not supported at all by Azure:

    e.g. www.level2.mydomain.com will result in a 404 error.

    Why is this important? in a multi tenant environment, with lots of customers on different subdomains, it is best from an end-user perspective to support a www. subdomain prefix, as that's what 99% of non-technerati do…

  6. Add button to copy Prod to Staging slot instead of swap

    When we deploy by using 'swap' the deployment slot will have an old version of the website. Since we want to use the deployment slot as a staging website, it would be great if we could copy the primary website to a deployment slot, without performing a swap.

  10. Ability to incrementally create/update AppSettings & ConnectionStrings

    Actual problem:
    Today if we don't provide all of the existing AppSettings or ConnectionStrings, the ones we omit are removed.

    Feature:
    A little bit like the ARM deployment mode, add the ability to specify an Incremental & Complete mode when pushing settings. To ensure compatibility, Complete would be the default, keeping the behavior we have today. If we set the mode to Incremental, only the provided settings would be created/updated, leaving existing settings untouched.

    Use cases:
    This would be very useful in cases where we want to sync AppSettings or ConnectionStrings for resources directly in our ARM templates for only…

  11. Provide .NET language packs on Web Apps

    I'm working on a website that uses System.ComponentModel.DataAnnotations

    On my local machine, model validation messages are displayed in french but they are in english when I deploy the website to Azure.

    Please install .NET language packs on Azure Web Apps so we don't have to create .resx files and messy code to override .NET built-in messages...

  12. Custom request headers in web server logs

    This is generally useful, but my usecase if with Cloudflare:

    When a web app is behind Cloudflare, all visitor IPs come Cloudflare's IPs. Cloudflare does forward the original visitor IP with a custom request header. I want to log this value in my web server logs. In IIS this is achieved with Advanced Logging, but this capability does not seem available in Azure web apps.

  13. Make OData a first class citizen.

    Apparently OData (Microsoft's flagship REST data protocol) isn't fully supported.

    More info:

    https://social.msdn.microsoft.com/Forums/azure/en-US/7363e392-86d8-4b60-99fd-af98e128ab06/whats-the-odata-story?forum=AzureAPIApps

    quote
    "If you can manually create Swagger 2.0 metadata to describe your REST API, it will work perfectly."
    /quote

    Assuming it's true that swagger can't do OData, I would think that fact alone would've precluded swagger as an option.

    Additionally, whatever the reason swagger cannot create metadata for a WebAPI OData project should have been addressed before launch.

    Regardless, please fix this.

  14. Static Web Apps support for generic SCM and CI/CD

    Static Web Apps, still in public preview as I'm writing this, only seems to integrate with Github and Github Actions.
    Even if we love Github, it would make sense to allow:


    1. Other Git repo such as Azure Repo, Gitlab, Bitbucket, ...

    2. Other CI/CD tools such as Azure Pipelines, Bitbucket Pipelines, Jenkins, ...

    In other words, exactly like normal Web Apps today.

  15. Online Certificate Status Protocol (OCSP) Stapling

    We are seeing some delays in Time To First Byte because OCSP stapling is not active on Azure Web Apps SSL endpoints.
    This causes our clients' browsers to call the issuing CA's endpoint before SSL negotiation can really begin.

    Stapling would save the client browser from having to make an extra request to the CA checking if the certificate has been revoked.

    There is also a potential privacy issue for our clients that the CA will be able to log these requests. If the web server takes care of OCSP on the other hand no requests will be sent from…

    We’ve started deploying the feature to a small set of stamps. We’ll continue to monitor the stamps for performance and validate if the feature is working as expected. Once we are confident there are no issues, we will roll out to all regions.

    Thanks,

  16. Metric and alert for Web App file system used quota

    We would like to setup an automatic alert that fires when the file storage of an app plan is reaching its limits.

    Ideally it will be great to have a metric that tells the % of storage (quota) consumed so we can set an alert on top of that metric.

  17. Enable 'Connect', 'Log Stream', 'Console' etc for App Service Environment

    When you deploy an App Service into an App Service Environment behind an ILB, much of the UI is greyed out. Examples of this is the 'Connect' button, 'Log Stream', 'Console' etc.

    I have to manually construct a URL to get to the kudu endpoint right now in order to use the console.

  18. BYO - Storage for Windows Web Apps

    It seems to me a little strange that I can mount Azure Files in App Service on Linux and Web App for Containers but not in standard/regular Web App.
    Our specific use case is a big web app spawned across more App Service Env under a Traffic Manager umbrella: for some kind of application logic a regular file system is better (more simple to use / less rework) than use the Storage API.

  19. The Always On setting should have an option to make it sticky to the slot when swapping

    This is odd it isn't this way by default but should at the very least have an option to make it sticky so as to not break anyone's current practices (in fact, shouldn't more settings have the option to be sticky?).

    The issue here is that an always on slot consumes resources. If for example each app consumes 200Megs of RAM, and I have 5 app services running on a service plan, each app service has 2 slots for swapping, then I need to have Always On turned on unnecessarily for 10 slots (2gigs of RAM consumed for nothing). The…

  20. Allow scale up to Premium V3 without redeploy or cloning

    When using an existing App Hosting Plan like S or Pv2 you can't scale to the new P*v3. It just says "Premium V3 is not supported for this scale unit." That last part is an easy sentence to write, but a much harder thing for us to execute.
    It would be great if we could have an option to migrate seamlessly to Pv3. Yes, it needs to migrate to a new scale unit that support Pv3, but it's much easier for Azure to manage all the things than doing it from User-Side.
