Stop forcing response headers

[bradlis7]

Can you please provide a config so that we can turn off the manipulation of cache HTTP headers? It makes ResponseCacheAttribute useless.

NCache/SessionState/ASP.NET Core/NCacheSessionServices/NCacheSessionServices/Utilities/SessionKeyManager.cs

Line 56 in b8bb6f0

context.Response.Headers["Cache-Control"] = "no-cache";

The best workaround I could come up with is something like this in Startup:

app.Use((context, next) => {
    context.Response.OnStarting(() => { 
        if (context.Items.Keys.Contains("_ncache-header-reset")) {
            var (cacheControl, pragma, expires) = ((StringValues, StringValues, StringValues))context.Items["_ncache-header-reset"];
            context.Response.Headers["cache-control"] = cacheControl;
            context.Response.Headers["pragma"] = pragma;
            context.Response.Headers["expires"] = expires;
        }
        return System.Threading.Tasks.Task.CompletedTask; 
    });
    return next.Invoke();
});
app.UseNCacheSession();
app.Use((context, next) => {
    context.Response.OnStarting(() => {
        context.Items["_ncache-header-reset"] = (context.Response.Headers["cache-control"], context.Response.Headers["pragma"], context.Response.Headers["expires"]);
        return System.Threading.Tasks.Task.CompletedTask;
    });
    return next.Invoke();
});
