How to disable browser cache in ASP.NET core rc2?
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")
});
}
Disabling browser cache in ASP.NET core:
public class HomeController : Controller
{
[ResponseCache(NoStore =true, Location =ResponseCacheLocation.None)]
public IActionResult Index()
{
return View();
}
}
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/[email protected]" />
<link rel="stylesheet" href="~/css/[email protected]" />
</environment>
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.
