How to disable browser cache in ASP.NET core rc2?

问题

I tried this Middleware but the browser still saving files.

I want user will always get the last version of js and css files.

public void Configure(IApplicationBuilder app)
{
    app.UseSession();
    app.UseDefaultFiles();
    app.UseStaticFiles(new StaticFileOptions
    {
        OnPrepareResponse = context =>
            context.Context.Response.Headers.Add("Cache-Control", "no-cache")
    });
}

回答1:

Try adding an Expires header as well:

app.UseStaticFiles(new StaticFileOptions()
{
    OnPrepareResponse = context =>
    {
        context.Context.Response.Headers.Add("Cache-Control", "no-cache, no-store");
        context.Context.Response.Headers.Add("Expires", "-1");
    }
});

Another approach would be to add a querystring that changes to the end of your requests in development. Middleware would not be required in this case.

<environment names="Development">
    <link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.css?@DateTime.Now.Ticks" />
    <link rel="stylesheet" href="~/css/site.css?@DateTime.Now.Ticks" />
</environment>

Disabling browser cache in ASP.NET core:

public class HomeController : Controller
{
    [ResponseCache(NoStore =true, Location =ResponseCacheLocation.None)]
    public IActionResult Index()
    {
        return View();
    }
}

Another way would be using an ASP-Attribute when you link your files in your _Layout.cshtml by using asp-append-version you will add a fresh hash everytime the file changed, so writing:

<script src="~/js/minime.js" asp-append-version="true"></script>

will in the end lead to:

<script src="/js/minime.js?v=Ynfdc1vuMOWZFfqTjfN34c2azo3XiIfgfE-bba1"></script>`

so you get caching and the latest version out of the box.
