我有这个例外:
Server Error in '/datalab' Application.
Request timed out.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.HttpException: Request timed out.
Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
Stack Trace:
[HttpException (0x80004005): Request timed out.]
但是我在 /datalab 和 /datalab/powerstats 目录中添加了一个 Global.asax 文件(datalab 目录是根目录,而超时的页面是 datalab/powerstats/output.aspx):
<%@ Application Language="C#" %>
<script runat="server">
void Application_Error(object sender, EventArgs e)
{
Exception exc = Server.GetLastError();
// Handle HTTP errors
if (exc.GetType() == typeof(HttpException))
{
Response.Write("<h2>Global Page Error</h2>\n");
// The Complete Error Handling Example generates
// some errors using URLs with "NoCatch" in them;
// ignore these here to simulate what would happen
// if a global.asax handler were not implemented.
if (exc.Message.Contains("NoCatch") || exc.Message.Contains("maxUrlLength"))
return;
//Redirect HTTP errors to HttpError page
//Server.Transfer("HttpErrorPage.aspx");
return;
}
}
</script>
我如何捕捉到这个异常?为什么不被caought?
