Setting Cache-Control Header on Static Files in a Maui Blazor App

Question

Hello,

Is there anyway to set the Cache-Control header on static files in a Maui Blazor App? It is currently set to the following values for all static files:

Cache-Control: no-cache, max-age=0, must-revalidate, no-store

In other Web Apps I have set it using app.UseStaticFiles in the Startup.cs file. Is there anything similar for a Maui Blazor App? Or is it possible to use custom middleware?

Thank you in advance!

As a Maui blazor app hosting the webview reads directly from the file system, there is no code to implement caching headers, nor do the static files get proceed by blazor.

TheMaui app could implement a caching strategy for the hosted webview, but it would vary by o/s

If the files are public urls, rather than wwwroot, the host controls caching tags.
