  2. 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.

  3. 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…

  6. 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…

  7. 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...

  8. 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.

  9. 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.

  10. 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.

  11. 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…

  15. Permission for accessing Performance counters

    We would like create a custom monitoring solution for our Azure Web Site based projects. Unfortunately the web site and job processes do not have permission to read performance counters.

    I understand that this is mandatory for a shared hosting environment. However I see nothing against having such functionality if the user has dedicated instances.

    Would it be possible to remove this restriction?

  17. Provide more secure TLS ciphers

    Currently Chrome flags the CBC ciphers as obsolete. CBC ciphers are at the top of the cipher preference list of Azure Web Apps as you can see there: https://www.ssllabs.com/ssltest/analyze.html?d=test.azurewebsites.net
    More info: https://www.chromium.org/Home/chromium-security/education/tls#TOC-Cipher-Suites

    So please provide some more secure ciphers from the ECDHE cipher suite like TLSECDHERSAWITHAES256GCMSHA384, TLSECDHERSAWITHAES128GCMSHA256, TLSECDHERSAWITHCHACHA20POLY1305SHA256.

  18. Allow FrontDoor CNAME for App Service Managed Certificate validation

    When creating an App Service Managed Certificate, it should allow validation if the CNAME is pointing to a FrontDoor with the same domain (or the FrontDoor's backend is the same Web App).

    Currently it gives the error "Hostname not eligible for App Service Managed Certificates creation" since the CNAME is not directly pointing to the web app.

  19. WebApp custom DNS with private DNS Name

    Custom DNS HostName for a WebApp is working exactly in the same way in both Azure and Azure Stack, with both ownership and record check against a public Internet DNS server. That's pretty cool for public facing web applications, but represents a security issue for :
    1)Intranet applications.(hosted on Azure or AzureStack)
    - Custom Domain Names makes sence not only for Internet but Intranet too.
    - We don't want to expose intranet application names publicly to the wild...
    2)Multi-tenant AzureStack

  20. Add support for NetworkWatcher / NSG Flow logs for App Service with Regional Vnet Integration enabled

    At the moment, if one uses an App Service with Vnet Integration there is NO way to monitor the traffic that traverses this path. For organizations with requirements to monitor ALL network traffic for integrity / Security / Audit purposes - this presents a significant challenge as ALL traffic that traverses this integration is not able to be monitored. Since the App Service presents itself as on a given subnet within the Vnet - there should be NO reason that NetworkWatcher or NSG flow logs shouldn't be usable.
