Add static IP address for outbound traffic without the use of App Service Environment
There are many reasons you may want to have a static IP address for outbound connections. For example, you may be accessing a system which requires you to whitelist IP address in a firewall, such as SQL Database or an external service.
Currently, the only way to get a static IP address for outbound connections is to use App Service Environment. App Service Environments are quite complex, and has a very high price tag. You need at least 4 instances, 2 of which must be P2, meaning you'll pay at least 1000 EUR/month. Paying 1000 EUR/month just because you want…

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…
728 votesWe may be adding 500 error messages to the App Service Environment capabilities, though we don’t have a timeline right now. We don’t have a way to add this to the multi tenant world.

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.

Add url-based probe health checks to Web Apps
When I spin up multiple instances of a Web App, and one of them goes unhealthy in the sense that it starts throwing HTTP 500 errors, I'd like the load balancer to take it out of the load, ideally by using load balancer probing.
This is achieved through WebRoles as detailed here: https://msdn.microsoft.com/library/azure/jj151530.aspx, but this functionality is not available in Web Apps. It would really help soften the blow of instance-based outages.

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…
397 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)

Enable 'client certificate authentication' per directory
I have a site that only part of it needs to be secured with client certificate authentication, it is able to be enabled on the site level but not the directory level as per this article.
https://docs.microsoft.com/en-us/azure/app-service-web/app-service-web-configure-tls-mutual-auth
365 votesHi,
thanks for the feedback. This is not currently possible as client cert auth on App Service is in require mode and as such cannot be delegated to folder level.We will review this item and your feedback, we may look to implement this capability based on customer prioritization.
Thanks

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...

Antimalware feature on Web Apps (App Service)
Cloud Services and Virtual Machines have an antimalware feature to protect themselves from viruses.
However, Web Apps only protects their platform, and there is no customer-facing antimalware service now.
If we develop an application which receives files from anonymous users with an upload form, we can't detect and get rid of the viruses.
We strongly request the antimalware feature like that Cloud Services and Virtual Machines do.210 votesThere are no near term plans to provide this functionality. However we will keep it under review for periodic re-evaluation in the future.
Thank you,

Add a web hook to get notified of completed auto-swaps
Deployment slots with the auto-swap feature are useful to warm up the application before making it visible. Unfortunately, it is not possible to get feedback from the operation.
It would be nice to have a web hook that is invoked with the result of the operation (success/failure).

Ability to suspend App Service Plans without charge
To save on costs, we want the ability to shut down an App Service Plan overnight while nobody is using it. We can shut down the Web App itself in an automated fashion, but the App Service Plan still charges us even through there are no running instances. Deleting and rebuilding the App Service and the App Service Plan is an option, but it is messy. Please consider not charging for periods where there are no running resources attached to the App Service Plan.
191 votesWe are leaving this idea open, though in the meantime note that you can scale down the App Service Plan to the free or shared tier to reduce costs.

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.

Add Application Initialization Support for Scale Up/Down
The application initialization/warmup feature works great when scaling out/in, but when scaling up/down requests are immediately routed to the new instances before the application is warmed up. It would be great if the new instances could be warmed up before rerouting requests to them.

Allow Azure App Service IP Restriction configuration by PowerShell Script
At the moment an Azure App service has the ability to white list IP addresses through the Networking > IP Restriction blade. It would be useful if this could be configured through PowerShell.

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.

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

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.

[Linux] Add support to mount Azure File Share to Web App For Container
Currently, if I try to follow the guide for Linux mapping of Azure File share inside a Web App for Container, I get the following error -

Use case for such scenarios is having a Wordpress website and running a cron job inside the container app to periodically upload the media folder to this File Share. This file share can then be mounted on the Dev VMs...
