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…

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.

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…
884 votesthis feature has been postponed as it wouldn’t be complete and might be revisited later if standards/supported features by CAs and browsers change (double wildcard certificates are not supported standard, resulting in no way to secure double wildcard domain)

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.

TLS 1.3 is now approved, this should be implemented with Web Apps
TLS 1.3 is now no longer a draft, when will Azure introduce the option to enable it?

Given TLS 1.2 was just enabled on Web Apps, we don’t have a plan for when the work will be done to enable 1.3. We will definitely leave this on the backlog as we will come back to it when relevant

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…396 votesThanks for the suggestion, we are looking into the feature request

Provide .NET language packs on Web Apps
I'm working on a website that uses System.ComponentModel.DataAnnotations

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.

Make OData a first class citizen.
Apparently OData (Microsoft's flagship REST data protocol) isn't fully supported.
More info:
quote
"If you can manually create Swagger 2.0 metadata to describe your REST API, it will work perfectly."
/quoteAssuming 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.

We would like to add more robust OData support. I am placing this item in “unplanned” to be used in future planning sessions.

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:- Other Git repo such as Azure Repo, Gitlab, Bitbucket, ...
- Other CI/CD tools such as Azure Pipelines, Bitbucket Pipelines, Jenkins, ...
In other words, exactly like normal Web Apps today.

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.

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…

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.

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.156 votesThank you for the feedback. There is some long-term work planned for the underlying VM’s that will enable users to simply “Scale Up” to the new hardware. This is a multi-milestone effort and we do not have an ETA at this time.

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.159 votesWe are working on enabling bring your own storage to Windows based Web Apps

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).

Web App for Containers - ACR access requires admin account enabled on repository
It looks as though Web App for Containers requires the use of the admin account on the repository in ACR.

Is there a plan to support Service Principal access to the ACR repository for Web App for Containers?
