Your pages will not timeout when you have debug=“true.” It
is simply because while debugging you will not really like it that you are in
middle of your debugging session and you get an error saying connection timed
out or something similar. This attribute allows you to debug your ASP.NET application
at your own pace. In the development box this makes sense, but in the
production server, long running requests may cause requests to queue and the
application to ultimately hang.
Let us check this since it is pretty simple. Ensure that
debug=“true” in the web.config file and build the website. Now, open one of the
files with .vb extension in your Temporary ASP.NET files folder. In the .vb
file, you will find a Public method called New().
Listing 1
Public Sub New()
MyBase.New
Dim dependencies() As String
CType(Me,System.Web.UI.Page).AppRelativeVirtualPath = "~/One.aspx"
If (Global.ASP.one_aspx.__initialized = false) Then
dependencies = New String(0) {}
dependencies(0) = "~/One.aspx"
Global.ASP.one_aspx.__fileDependencies = Me.GetWrappedFileDependencies(dependencies)
Global.ASP.one_aspx.__initialized = true
End If
Me.Server.ScriptTimeout = 30000000
End SubAs you can see above, this temporary .vb file was created
for One.aspx. Also notice that ScriptTimeout is set to 30 million seconds which
is approximately 347 days! This is the reason why your pages just will not time
out while debugging. If you turn debug=false (Figure 5), the .vb files itself
are no longer generated and eventually your pages will start expiring as usual.
The timeout of the requests are defined by httpRuntime element in your
machine.config (for .NET 1.1).
Listing 2
<httpRuntime
executionTimeout="90"
maxRequestLength="4096"
useFullyQualifiedRedirectUrl="false"
minFreeThreads="8"
minLocalRequestFreeThreads="4"
appRequestQueueLimit="100"
enableVersionHeader="true"
/>
In.NET 2.0 the httpRuntime element is not explicitly defined
either in the Machine.config file or in the root Web.config file. However, the
following settings are the default values as initialized by the system. If you
need to customize this section, you must create it in your configuration file
and define only those attributes that need customization.
Listing 3
<httpRuntime
executionTimeout="110"
maxRequestLength="4096"
requestLengthDiskThreshold="256"
useFullyQualifiedRedirectUrl="false"
minFreeThreads="8"
minLocalRequestFreeThreads="4"
appRequestQueueLimit="5000"
enableKernelOutputCache="true"
enableVersionHeader="true"
requireRootedSaveAsPath="true"
enable="true"
shutdownTimeout="90"
delayNotificationTimeout="5"
waitChangeNotification="0"
maxWaitChangeNotification="0"
requestPriority="Normal"
enableHeaderChecking="true"
sendCacheControlHeader="true"
apartmentThreading="false"
/>
