How to: Set default path to ASP.Net Core routing

I want to serve two ASP.Net web applications from the same server. One is MVC - which is the main site - and the other Blazor - which is a side application that will be called from the main site.

I have bound the two apps to different ports:

Blazor: webBuilder.UseUrls("http://0.0.0.0:5001");
MVC: webBuilder.UseUrls("http://0.0.0.0:5000");

I have set up Apache as a proxy and requests are directed like this:

    ProxyPass /blazor http://127.0.1.1:5001/
    ProxyPassReverse /blazor http://127.0.1.1:5001/
    ProxyPass / http://127.0.1.1:5000/
    ProxyPassReverse / http://127.0.1.1:5000/

The proxy works but the Blazor app doesn't work correctly as the rounting and data folders don't preceed their calls with /blazor.

In order to get the Blazor app to work correctly I assume I need to alter the default path for routing in code, but I'm not sure how to go about this.

I suspect I need to pass IApplicationBuilder:UseRouting() the info....

can anyone assist?

Thanks

Found the answer...

By the way, I am using Asp.Net Core 3.1.

Two things need to be done:

Add a call to IApplicationBuilder:UsePathBase() as the first item in the app's Configure() method:

app.UsePathBase("/appname");

And ensure that the proxy appends the "/appname" when forwarding the request to Kestrel. In Apache, simply add it like this:

ProxyPass /blazor http://127.0.1.1:5001/blazor
ProxyPassReverse /blazor http://127.0.1.1:5001/blazor

The app will append this to all subsequent requests within the app.
