  1. Azure Web App auth customize WWW-Authenticate challenge

    Support authorization_uri in Azure AD Pre-Auth for Web Apps

    https://stackoverflow.com/questions/46908858/azure-web-app-auth-customize-www-authenticate-challenge

    According to some docs (https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-protocols-oauth-code#use-the-access-token-to-access-the-resource), the WWW-authenticate header should return authorization_uri like this:

    HTTP/1.1 401 Unauthorized
    WWW-Authenticate: Bearer authorization_uri="https://login.microsoftonline.com/contoso.com/oauth2/authorize", error="invalid_token", error_description="The access token is missing.",

    But since we use the pre-authentication features of Azure Web Apps, we can't control that directly from code.

    • [Azure web app LINUX] VSTS deploy to slot

      Currently I am using VSTS for my CI/CD to azure web app linux
      However, unfortunately, there's still a pretty significant downtime for every deployment.

      I tried to create a staging slot to minimize the downtime, and swap to production. however, VSTS doesn't allow me to deploy to my staging slot.

      I created a github issues too here https://github.com/Microsoft/vsts-tasks/issues/4460

      If I can't deploy to my slot, what's the point of having slot in the first place? Please prioritize this as I think this is a pretty important feature

      • Access all quotas & limits on websites to determine bottlenecks

        Running a site on a PaaS is a wonderful thing until you hit boundaries and lack transparency to quickly respond to issues.
        Especially because the times you're hitting those issues are usually very time critical!

        E.g. we had a Web App scaled out to 6 servers but noticed that we had major performance issues even though the CPUs were only at 10% the database DTU usage was only at 1% and any available metric was in a very reasonable range.
        Only after many hours intense back and forth with the support team were we able to determine that we're hitting…

          This is started but not in the manner you might expect. We are making a number of changes so that you will not hit an IOPS limit issue anymore.
          As a general rule though, we do try to push up information when quotas are hit.

        • Show the current github configured branch

          Currently you have to use the Resource Explorer to figure out/remember which GitHub branch you had configured. This is pretty inconvenient. Even showing it in the logs would be more useful.

          • Add Quota and Set Retention Setting from ASM to ARM Portal

            Could the Quota and Set Retention Setting from the Classic Azure Portal Web App -> Configure -> Site Diagnostics be moved over to the ARM Portal. These are two pretty important settings that seem to be missing from the new App Services -> Settings -> Diagnostics logs blade.

            • Show Deployment Source

              Add the ability to view the "Deployment source" settings for a Web App.
              Example: When setting the Deployment Source for a Web App, if you select Drop Box as a source and provide a directory, the Management UI doesn't show you what directory the deployment is coming from after it has been set. It would be nice to be able to see what the directory was so you can confirm it is coming from the right directory without having to Disconnect and Reconnect the deployment source.

              • Increase the size limitation of backups from 10GB to the max size of the webapp

                We have standard S3 webapps which allow you to have 50 GB of local storage. However our backups continue to fail because our site uses 14 GB. Even after adding filters, it's almost impossible to get under the 10 GB limit, rendering backups useless for us

                • Enable HTTP/2 on Azure Web Apps

                  IIS 10.0 in Windows 10 already supports HTTP/2, Azure Web Apps should support it as well.

                    Hi all. As everyone had noticed, we have upgraded App Service resources to Server 2016. As mentioned in our updates, this is indeed paving the way to HTTP/2 support across the board. As we are settling in with stability of the new OS version, we will begin work to open up HTTP/2. When I have a concrete timeline to share, I will do so. We should expect that in the next few months.

                    Thanks,
                    Oded

                      Hi all,

                      Our team is discussing how best to approach a solution to the request here and we’ve come up with a partial solutiuon which would be great to get feedback on.

                      The proposed solution to rename the App Service Plan is to:
                      1- Create a new App Service Plan with the desired new name, the new App Service Plan needs to be in the same Resource Group as the original App Service Plan.
                      2- Move the apps in the original ASP to the new ASP using the steps mentioned here: https://docs.microsoft.com/en-us/azure/app-service/azure-web-sites-web-hosting-plans-in-depth-overview#move-an-app-to-a-different-app-service-plan

                    • Add native sitecore site support

                      It would be nice if you add native sitecore site support to your azure websites. Like you have with Umbraco.
