NameDescription
System_CAPS_pubeventCreating

Occurs when a new anonymous identifier is created.

The AnonymousIdentificationModule class creates and manages anonymous identifiers for an ASP.NET application. Anonymous identifiers are used by features that support anonymous identification such as the ASP.NET System.Web.Profile.

The AnonymousIdentificationModule exposes a Creating event that enables you to set the anonymous identifier to a custom value. If you do not specify a custom anonymous identifier value, a Guid is used.

The Creating event is accessed by specifying a subroutine named AnonymousIdentification_Creating in the Global.asax file for your ASP.NET application.

The AnonymousIdentificationModule is only used when anonymous identification is Enabled by setting the enabled attribute of the configuration element to true.

System_CAPS_noteNote

Anonymous identification is independent of any type of ASP.NET authentication.

The following code example shows a Web.config file for an application that enables anonymous identification.

<configuration>
  <system.web>
    <authentication mode="Forms" >
      <forms loginUrl="login.aspx" name=".ASPXFORMSAUTH" />
    </authentication>

    <anonymousIdentification enabled="true" />

    <profile defaultProvider="AspNetSqlProvider">
      <properties>
        <add name="ZipCode" allowAnonymous="true" />
        <add name="CityAndState" allowAnonymous="true" />
        <add name="StockSymbols" type="System.Collections.ArrayList" 
          allowAnonymous="true" />
      </properties>
    </profile>
  </system.web>
</configuration>
