    if ( $webAppPool -ne $null ) {
        
        #For all web sites
        #$webSites = Get-ChildItem 'IIS:\Sites'
        
        #For only 'Default Web Site'
        $webSites = Get-ChildItem 'IIS:\Sites' | where { $_.Name -eq 'Default Web Site' }
        
        $webSites | % {
            $webApplications = Get-ChildItem ( Join-Path 'IIS:\Sites' $_.Name ) |
                where { $_.NodeType -eq 'application' }

            $webFolders = Get-ChildItem ( Join-Path 'IIS:\Sites' $_.Name ) |
                   where { $_.NodeType -eq 'directory' }
            
                            
            $result += $webApplications |
                where { $_.applicationPool -eq $webAppPoolName }
