The WebRequestInformation type exposes the following members.

Public propertyPrincipalGets the instance of the managed-code principal associated with the Web request.
Public propertyRequestPathGets the physical path of the Web request.
Public propertyRequestUrlGets the logical path of the request.
Public propertyThreadAccountNameGets a string that represents the Windows logon name of the user on whose behalf the code is being run.
Public propertyUserHostAddressGets the user host address.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodFormatToStringFormats the Web-request information.
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

ASP.NET health monitoring allows production and operations staff to manage deployed Web applications. The System.Web.Management namespace contains the health-event types responsible for packaging application health-status data and the provider types responsible for processing this data. It also contains supporting types that help during the management of health events.

Instances of the WebRequestInformation class contain information that is obtained using the WebRequestEvent, WebAuditEvent, WebErrorEvent, or WebRequestErrorEvent types.

Your application needs the appropriate permissions to access protected information provided by this type.


In most cases you will be able to use the ASP.NET health-monitoring types as implemented, and you will control the health-monitoring system by specifying values in the healthMonitoring configuration section. You can also derive from the health-monitoring types to create your own custom events and providers. For an example of creating a custom event class, see the example provided in this topic.

The following code example shows how to implement a custom event that uses the WebRequestInformation type.

Also shown is an excerpt of the configuration file that enables ASP.NET to use this custom event.

Ensure that your custom event is raised at the proper time, that is, when the equivalent system health event it replaces would be raised.

  heartBeatInterval="0" enabled="true">

    <add name="Custom" 
      minInterval="00:00:00" />


      type="SamplesAspNet.SampleWebRequestInformation,webrequestinformation,Version=1.0.1782.28745, Culture=neutral, PublicKeyToken=79955d9b8521c250,processorArchitecture=MSIL" />



    <add name="Custom Web Request Info Event" 
      profile="Custom" />
