"PushPromise" .NET 4.6.1を使用してHttp2プッシュサーバー機能を実装しようとしていますが、これはRazorの「html拡張子」を持っていますページを構築するためのRazorエンジン）。 ASP.Net HTTP2 PushPromiseが遅い
public static IHtmlString PushPromiseStylesheet(this HtmlHelper htmlHelper, string src, bool addDomElement = true)
{
var context = HttpContext.Current;
var path = System.Web.Optimization.Styles.Url(src).ToString();
var headers = new NameValueCollection { { "accept-encoding", context.Request.Headers["accept-encoding"] } };
context.Response.PushPromise(path, "GET", headers);
var styleElement = $"<link rel=\"preload\" href=\"{path}\" as=\"style\">";
return new HtmlString(addDomElement ? styleElement : String.Empty);
}
public static IHtmlString PushPromiseJavascript(this HtmlHelper htmlHelper, string src)
{
var context = HttpContext.Current;
var path = System.Web.Optimization.Scripts.Url(src).ToString();
var headers = new NameValueCollection { { "accept-encoding", context.Request.Headers["accept-encoding"] } };
context.Response.PushPromise(path,"GET",headers);
var javascriptElement = $"<link rel=\"preload\" href=\"{path}\" as=\"script\">";
return new HtmlString(javascriptElement);
}
public static IHtmlString PushPromiseImage(this HtmlHelper htmlHelper, string src, bool addDomElement = false)
{
var context = HttpContext.Current;
var path = System.Web.Optimization.Scripts.Url(src).ToString();
var headers = new NameValueCollection { { "accept-encoding", context.Request.Headers["accept-encoding"] } };
context.Response.PushPromise(path,"GET",headers);
var imgElement = $"<link rel=\"preload\" href=\"{path}\">";
return new HtmlString(addDomElement ? imgElement : String.Empty);
}
public static IHtmlString PushPromiseWebFont(this HtmlHelper htmlHelper, string src, string type = null)
{
var context = HttpContext.Current;
var path = System.Web.Optimization.Scripts.Url(src).ToString();
type = string.IsNullOrWhiteSpace(type) ? "font/woff2" : type;
var headers = new NameValueCollection { { "accept-encoding", context.Request.Headers["accept-encoding"] } };
context.Response.PushPromise(path, "GET", headers);
var fontElement = $"<link rel=\"preload\" href=\"{path}\" as=\"font\" type=\"{type}\"> ";
return new HtmlString(fontElement);
}
