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.

Marking as complete! Full deployment for all multi-tenant resources is now complete. Enabling HTTP/2 is documented in the blog here:
https://blogs.msdn.microsoft.com/appserviceteam/2018/04/13/announcing-http2-support-in-azure-app-service/

We will have UI support in the Azure Portal in the coming weeks for a simple toggle experience but you can update through the resource explorer right now.

Deployment to App Service Environmentx and national clouds will be coming shortly.

Please reach out over the developer forums for any questions or issues encountered.

Thanks,
Oded

If we don’t have any surprises, this should be delivered in the next few weeks.

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,

Thank you for your patience. As you saw, we are updating App Service infrastructure to Server 2016. This will definitely pave the way to HTTP/2, but more updates in this regard will come once the update to 2016 is complete.

We’re excited this is finally coming along!

Thank you,
Oded

Hi all,

I’m happy to share that work has officially started to enable HTTP/2 for App Service. We will share a more concrete timeline as it becomes available, but we are hoping for sometime later this year. We really appreciate your patience as we work through multiple dependencies that have to be met before we can fully support HTTP/2.

Thanks,
Oded

Current status is that the feature is definitely still on the roadmap for implementation. However as noted previously, there are no timeline updates at this time.

Thanks,

Thanks Martin! As our environment is quite large, it will take us a while to upgrade our boxes. We are not ready to announce a timeline yet.
Thanks!

Can we participate in a preview, we're running into buffer to small options in production.

Most modern browsers either have H2 support or have it coming soon. Would be great to build this support in now. Browser's that don't yet support just fall back to http/1.1. This will also support those that are now using PWA. Without this Azure will not have the ability to support the leading edge of web development for front-end engineers.

Hi, HTTP2 is rapidly becoming the standard for new HTTP APIs. As Azure Functions focused on being an API (and a trigger system), it should definitely support HTTP2 ASAP. Thanks!

Hi Oded, is Azure Functions part of App Service? Will it get HTTP2 also? Thanks

Hi, I can't find anything regarding Azure Functions and HTTP2. I desperately need HTTP2 support and really want to opt for Functions as my main API solution. Will this project supply HTTP2 for Functions? Thanks

I am also keen on getting Windows 2016 for my app service due to the bug described here https://github.com/dotnet/corefx/issues/7812

What is ETA from Web API on windows 2016? currently due bugs in Windows 2012 ( https://github.com/dotnet/corefx/issues/7812 ) i'm getting 1.3% of calls failing with "The buffers supplied to a function was too small"

As a first step we intend to preview HTTP/2 for public App Service, then at a later point, move to App Service Environment. ASE presents some challenges and it's not as straightforward as ASE gets in for free once enabled for App Service.

Thanks,
Oded

The Windows Web Apps still run on VMs with Server 2012 (not even 2012 R2).
They would have to upgrade them all to run on Server 2016 to use IIS capable of supporting HTTP/2.
Not sure how they handle upgrades like this. VMs get new versions. Wonder if Web Apps can also get a new version?
