SharePoint Sites and Pages Powershell Warmup Script

Very nice little script i created to warmup all PWA pages and workspaces.
Simply replace the SiteURL and the SitePages with your own values and place the code in a file named "SharePointWarmup.ps1".
Run the script in Powershell or Task Scheduler.

 $SiteURL = "http://intra/PWA/"  
 $SitePages =   
 "default.aspx",  
 "projects.aspx",  
 "ProjectBICenter/_layouts/15/xlviewer.aspx?id=/PWA/ProjectBICenter/Sample%20Reports/Projectum/DailyCommentsReport%20v7%20-%20PowerView.xlsx&Source=http%3A%2F%2Fintra%2FPWA%2FProjectBICenter%2FSample%2520Reports%2FForms%2FAllItems%2Easpx%3FRootFolder%3D%252FPWA%252FProjectBICenter%252FSample%2520Reports%252FProjectum%26FolderCTID%3D0x012000271EBEF22B819D4AA417BE3C68ADBA34%26View%3D%257B857402E5%252DF616%252D4DC2%252DA880%252D5CFC03D52EFA%257D",

 function HitPage($url)  
 {  
   try   
   {   
     Write-Host "Hitting page: $url"   
     $wc = New-Object WarmupWebClient($timeout)   
     $wc.Credentials = [System.Net.CredentialCache]::DefaultCredentials   
     $ret = $wc.DownloadString($url)   
   }  
   catch [Exception]   
   {   
     Write-Host "Failed to hit page. Message was: $($_.Exception.Message)"   
   }   
 }  
 foreach ($site in $SitePages)   
 {   
   $warmupSite = $SiteURL + $site  
   HitPage($warmupSite)  
 }  
 Write-Host "All sites have been hit"   

Of cause you want this script to be run on a timely schedule so remember to check out my other post on how to do exactly that Run Powershell from Task Scheduler .
