我在我们的生产网站上看到这个，以及一个小的测试网站，我只是为了测试这个…
基本上，似乎由mvc处理的请求永远不会超时。我在我的web.config中设置了一个executionTimeout并关闭调试模式。然后我添加了一个无限循环的thread.sleeps到一个常规aspx页面和一个mvc页面(循环是在mvc页面的控制器)。 aspx页面可靠超时(HttpException(0x80004005)：请求超时。)，但是mvc页面只是旋转永远没有超时。
有没有单独的设置mvc(我看过，但没有找到它们)？ Do mvc请求默认不超时？
任何帮助，这将不胜感激。我会很高兴地发电子邮件发送我的小测试网站，如果它会帮助任何人。
编辑：我使用MVC3。

解决方法
我找到了这个的原因，methinks：
此方法在WrappedAsyncResult类中，MvcHandler类通过BeginProcessRequest使用该类：
public static IAsyncResult BeginSynchronous<TResult>(AsyncCallback callback,object state,Func<TResult> func,object tag)
{
BeginInvokeDelegate beginDelegate = delegate (AsyncCallback asyncCallback,object asyncState) {
SimpleAsyncResult result = new SimpleAsyncResult(asyncState);
result.MarkCompleted(true,asyncCallback);
return result;
};
EndInvokeDelegate<TResult> endDelegate = _ => func();
WrappedAsyncResult<TResult> result = new WrappedAsyncResult<TResult>(beginDelegate,endDelegate,tag);
result.Begin(callback,state,-1);
return result;
}
其中“Begin”是：
public void Begin(AsyncCallback callback,int timeout)
{
bool completedSynchronously;
this._originalCallback = callback;
lock (this._beginDelegateLockObj)
{
this._innerAsyncResult = this._beginDelegate(new AsyncCallback(this.HandleAsynchronousCompletion),state);
completedSynchronously = this._innerAsyncResult.CompletedSynchronously;
if (!completedSynchronously && (timeout > -1))
{
this.CreateTimer(timeout);
}
}
if (completedSynchronously && (callback != null))
{
callback(this);
}
}
编辑：提出了一个ham-handed的方式强制MVC控制器的行动“超时”，虽然机制有点粗暴：
public class TimeoutController : Controller
{
private bool _isExecuting = false;
private int _controllerTimeout = 5000;
private Thread _executingThread;
private readonly object _syncRoot = new object();
protected override void ExecuteCore()
{
_executingThread = Thread.CurrentThread;
ThreadPool.QueueUserWorkItem(o =>
{
Thread.Sleep(_controllerTimeout);
if (_isExecuting)
{
_executingThread.Abort();
}
});
base.ExecuteCore();
}
protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
_isExecuting = true;
base.OnActionExecuting(filterContext);
}
protected override void OnActionExecuted(ActionExecutedContext filterContext)
{
_isExecuting = false;
base.OnActionExecuted(filterContext);
}
public int ControllerTimeout
{
get
{
int retVal;
lock(_syncRoot)
{
retVal = _controllerTimeout;
}
return retVal;
}
set
{
lock(_syncRoot)
{
_controllerTimeout = value;
}
}
}
}
