If we need to add some URL rewrite to a SharePoint site, we can do that using some web.config settings like :
<rewrite>
<rewriteMaps>
<rewriteMap name=”Redirects”>
<add key=”/Page1.html” value=”/Page1″ />
<add key=”/Page2.html” value=”/Page2″ />
</rewriteMap>
</rewriteMaps>
</rewrite>
One way to do that Is to use SharePoint Powershell commands.
The following script achieves that:
[Microsoft.SharePoint.Administration.SPWebConfigModification] $modification = New-Object Microsoft.SharePoint.Administration.SPWebConfigModification
$modification.Path = “configuration/system.webServer”;
$modification.Name = “rewrite”;
$modification.Sequence = 0;
$modification.Owner =$Owner;
$modification.Type = 0 # EnsureChildNode;
$modification.Value = “”;
$webApp.WebConfigModifications.Add($modification);
$modification = New-Object Microsoft.SharePoint.Administration.SPWebConfigModification
$modification.Path = “configuration/system.webServer/rewrite”;
$modification.Name = “rewriteMaps”;
$modification.Sequence = 0;
$modification.Owner =$Owner;
$modification.Type = 0 # EnsureChildNode;
$modification.Value = “”;
$webApp.WebConfigModifications.Add($modification);
$modification = New-Object Microsoft.SharePoint.Administration.SPWebConfigModification
$modification.Path = “configuration/system.webServer/rewrite/rewriteMaps”;
$modification.Name = “rewriteMap”;
$modification.Sequence = 0;
$modification.Owner =$Owner;
$modification.Type = 0 # EnsureChildNode;
$modification.Value = “”;
$webApp.WebConfigModifications.Add($modification);
$modification = New-Object Microsoft.SharePoint.Administration.SPWebConfigModification
$modification.Path = “configuration/system.webServer/rewrite/rewriteMaps/rewriteMap”;
$modification.Name = “redirect-1”;
$modification.Sequence = 0;
$modification.Owner =$Owner;
$modification.Type = 0 # EnsureChildNode;
$modification.Value = “”;
$webApp.WebConfigModifications.Add($modification);
$modification = New-Object Microsoft.SharePoint.Administration.SPWebConfigModification
$modification.Path = “configuration/system.webServer/rewrite/rewriteMaps/rewriteMap”;
$modification.Name = “redirect-2”;
$modification.Sequence = 0;
$modification.Owner =$Owner;
$modification.Type = 0 # EnsureChildNode;
$modification.Value = “”;
$webApp.WebConfigModifications.Add($modification);
$webApp.Update()
$webApp.Parent.ApplyWebConfigModifications()
do{
Start-Sleep -Seconds 2;
Write-Host “.” -NoNewline
$configJobRunning = IsWebConfigModificationJobPendingOrRunning $webApp;
}while ($configJobRunning);
