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…

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…

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.
604 votesHi everyone,
Use Proactive Auto Heal to set up rules (such as for high HTTP 500 errors) and actions (such as restarting the instance).

Provide a real support for integrating Web Apps with resources inside a virtual network
The current implementation of Vnet integration with Web Apps is nowhere near good enough.
1. ASE's: ASE's are fine, but the extreme cost makes it completely unrealistic to use the feature except for very large sites.
2. Point-to-Site Vnets: If my vnet is an Expressroute vnet then I have no way to connecto to it using this featureWe need a well-working and easy way of integrating webapps with vnets. The optimal solution would be a simple "yes/no" for giving the web app an ip address inside the virtual network.

We have started work on the Vnet integration for Linux sites. The feature is currently in preview.

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.

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
432 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

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…
415 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)

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.286 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).

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.

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.
211 votesThank you for your feedback!
We would like to add more robust OData support. I am placing this item in “unplanned” to be used in future planning sessions.

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.

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…

Scale Out wait for WarmUp complete before being added to LoadBalancer
When adding new instances to the LoadBalancer, scale out mechanism doesn't wait for those application instances to fully warm up.
Availability checker, via AppInsights, logs these responses, with the header:
'X-AppInit-WarmingUp: 1'Which means that IIS knows that the application is in it's WarmUp cycle, but the LoadBalancer is already trying to serve requests.
N.B. we _can_ add a rewrite rule to redirect the user to the original request, and hope that the LoadBalancer sends the user to a ready instance - but this feels like a hack.
167 votesThanks for the feedback. We are thinking of ways to make the warmup model better and fully ready for the app’s traffic. Right now, we just see the instance is ready before directing traffic.
Please refer to this blog post for more information about slots and AppInit.

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:

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.
