OutputCache多个域名下会记录相同页面问题

[OutputCache(Duration = PresetLang.CACHE_DURATION, VaryByCustom = "HomeIndex")]

public ActionResult Index()

{

Response.Cache.SetOmitVaryStar(true);

}

Global.asax.cs

//已用户当前的URL作为缓存Key

public override string GetVaryByCustomString(System.Web.HttpContext context, string custom)

{

var urlCache = WebCache.Get<string>(context.Request.Url.Host);

if (urlCache == null)

{

urlCache = string.Format("{0}{1}", context.Request.Url.ToString(), Guid.NewGuid());

WebCache.Add<string>(context.Request.Url.Host, urlCache);

}

return urlCache;

//string requestUrl = context.Request.Url.ToString();

//return requestUrl;

}
