I have a project in Django and i want to use django channels for support websockets in my project, but i have a problem with IIS configuration. Could somebody helps me with configuration daphne in IIS or configuration IIS to support channels and daphne. Has somebody any expierence in it? And maybe somebody knows some ways to deploy django+channels on IIS with or without daphne?
Sorry for my bad english.

Hi,

I am afraid I don't have experience using IIS - I don't know if it even supports HTTP/1.1 proxying, which is needed for WebSockets. Hopefully someone else can help.

There exists 3rd party ASGI handler for IIS: https://github.com/mjkillough/iis-asgi-handler/ 

It also requires at least IIS 8 and websocket protocol installed. More details at https://www.iis.net/learn/get-started/whats-new-in-iis-8/iis-80-websocket-protocol-support

Note, you need to build that handler yourself, which then requires another set of tools, visual studio 2015 and CMake 2.8+

Also note that there is not much of installation instructions or how to build package that you can just install to your server without installing all the development tools there.

I really suggest that you try to find some *nix platform to run required parts, it's just plain simpler and more documented than IIS.

Thank you for your answers and advices. I have no possibility to use *nix platform, my employer wants it on IIS. I'll try to build it, thank you very much!

if you are stuck on windows but not necessarily IIS you may try cygwin, I once had to deploy on windows and after investigating some possibilities I just installed cygwin and put nginx with uwsgi.

Yes you can.
daphne -e ssl:443:privateKey=key.pem:certKey=crt.pem django_project.asgi:channel_layer

For more info look at the Daphne GitHub repo https://github.com/django/daphne/

But I would suggest run Nginx in front of the Daphne which will handle SSL.

I have IIS, and i ran IIS in front of Daphne which handle SSL. But when i run daphne to listen port which support https in IIS, daphne tell me

I tried different ports, which allowed in firewall. What i am doing wrong?

Hi,

Most probably accesses to ports below 1024 requires that you start daphne from administrator elevated prompt.

First off I love this project. Django Channels is amazing!

I just wanted to see if anyone has had any success with using iis with Django-Channels since this post over 2 years ago.

Thank you!

It looks like I found my key I had to install the application module CGI then use this library to get everything to work!

Does that support websockets? 

IIS itself seems to ( https://docs.microsoft.com/en-us/iis/get-started/whats-new-in-iis-8/iis-80-websocket-protocol-support ) , but I don't the factcgi ->wsgi adaptor does.

I've used it for non-channels projects, but didn't think it would support websockets; and channels - for a start it's WSGI not ASGI.

Or have I missed something.

No you haven’t missed anything I spoke too soon. I was able to get the regular site running using fastcgi. I hope to revisit this once the regular site is in production. It’s too bad we are on Windows server R2

My plan to get this to work is to have daphine handle websockets and iis normal http. I don’t know how to configure iis to allow that though. Any ideas or direction would be much appreciated
