Authentication for an app behind reverse proxy


I’ve been successfully using a custom OAuth provider for my panel app. However I’m now working on a new production environment where my app is behind a reverse proxy so that users can access the app on standard ports.

I followed the bokeh docs on setting up a reverse proxy with apache and it works well. But now I’m stuck when it comes to adding authentication. When typing http://address/myapp, the url becomes http://address/login?next=%2Fmyapp and yields a Not Found page. I’ve tried various ProxyPassMatch patterns to try to pass the url parameters correctly, to no avail.

Does anyone have any experience on this, be it with apache or nginx?

Here is a config that works. However, I also had to modify the module in Panel (see issue).

ProxyPass /myapp/ws ws://
ProxyPassReverse /myapp/ws ws://

ProxyPass /myapp/static
ProxyPassReverse /myapp/static

ProxyPassMatch /myapp/(.*)$$1
ProxyPassReverse /myapp/(.*)$$1

Redirect /myapp /myapp/

Alias /static /path/to/bokeh/server/static
<Directory /path/to/bokeh/server/static>
Options +Indexes

I also use would like to use azure oauth and then reverse proxy with nginx. Trying to follow along with what you are adding on your nginx config. Where do i need to plug the above into?

Soooo… my error was not with source code. Azure auth redirect to reverse proxy requires adding to nginx config
