find whether the current user is a member of a specific audience?

Question

I am trying to find whether the current user is a member of a specific audience and used the below code however it returns "false" though the user belongs to the "testing" audience.

Microsoft.Office.Server.Audience.AudienceManager.IsCurrentUserInAudienceOf("Testing",false)

what would be the issue?

Update:

AIM:
We would like to redirect the user based on the audience group.

Eg.,
If Userx is a member of the audience "Testing", he will be redirected to "newWeb" otherwise to "oldWeb".

Implementation:
DelegationControl loads a user control, validation & redirection is taken place on the user control.

Update-2:

Tried the below code however getting the "Access denied" error message while trying to get the audience - "Audience audience = audienceManager.GetAudience("Testing");", have verified and found that the app., pool has full control on the user profile application.

else {
SPUser currentUser = SPControl.GetContextWeb(Context).CurrentUser;
SPSecurity.RunWithElevatedPrivileges(delegate
{
//HttpContext httpCtxt = HttpContext.Current;
//HttpContext.Current = null;
Microsoft.Office.Server.Audience.AudienceManager audienceManager = new Microsoft.Office.Server.Audience.AudienceManager(SPServiceContext.Current);
Audience audience = audienceManager.GetAudience("Testing");
//HttpContext.Current = httpCtxt ;
if ( audience.IsMember(currentUser.LoginName))
{
Page.Response.Redirect("http://www.redirectNew.com");
}
else
{
Page.Response.Redirect("http://www.redirectOld.com");
}
});
}

Answer 1

AudienceLoader objAudLoader = AudienceLoader.GetAudienceLoader();
AudienceManager.IsCurrentUserInAudienceOf(objAudLoader, audience, false)

The AudienceLoader belongs to Microsoft.Office.Server.Audience namespace and documented here: http://msdn.microsoft.com/en-us/library/microsoft.office.server.audience.audiencemanager.iscurrentuserinaudienceof.aspx

UPDATE

If you still see unexpected results, look for an exception right about the same time it returns false. I realize SharePoint returns false when there is an unexpected error encountered.

Step 1

The AudienceLoader class is just a cache of the user's audience information and so it can sometimes give some misleading results. Try using the Audience.IsMember function instead:

Audience audience = audienceManager.GetAudience("Testing");
SPUser currentUser = SPControl.GetContextWeb(Context).CurrentUser;

if (audience.IsMember(currentUser.LoginName))
{
    // Redirect user to newWeb
}
else
{
    // Redirect to oldWeb
}

Here are some other supporting cases:

Step 2

Since changes made to audiences and audience rules are not reflected in the audience membership until it has been compiled, you will need to recompile your audiences in Central Administration before programatically performing the checks above.

Try AudienceManager.IsMemberofAudience
