Set nginx config

jason

Is it possible to set nginx config for an app listening on a port? i.e - the nginx equivalent of an .htaccess file? Specifically, I need to override the default proxy_set_header config value, otherwise I've got a show-stopper where kestrel and nginx aren't playing nicely.

jason not at the time, please email support to let us know the specifics. If this is something that you were doing at WebFaction and it's not working here then we'll try to sort it out.

Just in case anyone else is looking at this with a similar situation (i.e - a "Connection: Upgrade" http header set by the front-facing nginx server is breaking requests to Kestrel/dotnet core), here's what I did:

Create a PHP/Apache application to serve as a reverse proxy to your dotnet api.

Add the following config:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^proxy.your-account.opalstacked.com$ [NC]
RewriteRule ^(.*)$ http://localhost:1234%{REQUEST_URI} [P,NC,L,QSA]

where 1234 is the port that your existing dotnet app is listening on.

Have your client use the proxy url instead of the url of your API, or just set up your proxy to handle the route that your API was handling prior.
