I am using the Angular project template with ASP.NET Core. Reference
The caching should be enabled by default, to be sure I have added an StaticFileOptions object to the StaticfileMiddleware:
public class Startup
{
// ...
app.UseStaticFiles(new StaticFileOptions
{
OnPrepareResponse = ctx =>
{
const int durationInSeconds = 60 * 60 * 24;
ctx.Context.Response.Headers[HeaderNames.CacheControl] ="public,max-age=" + durationInSeconds;
}
});
// ...
}Then I have created an test.html in wwwroot folder.
<!DOCTYPE html><html lang="en"><head><meta charset=utf-8><title>Test static files</title></head><body>
This is a test for static files!</body></html>When I dotnet run and navigate to https://localhost:5001/test.html the page is displayed correctly.
After I change the html page, I click to google chrome's address bar and press enter, to issue another HTTP request to the test.html file. I have not reload the page.
You can see that the change is reflected by google chrome and I received an status 200 again instead of 304. Cache-control in the Response Header is public,max-age=86400. Why does the static file caching not work? My desired result would be that the change is not reflected after the second HTTP request, so I can be sure static file caching is working properly.
I am using: .NET Core SDK 3.1.201 and Chrome 80.0.3987.163.
