Disable output caching for site or pages

Question

How to disable output caching for site pages?

I tried disabling output caching from Site settings but I could not see any output caching in the Site setting collection administration menu, even in publishing infrastructure mode.

I want to know how I could make this change with PowerShell. I also want to disable caching on the page level.

   //I tried this on a page but it rises an error:
   <%@ OutputCache Location="None" %>

How can this be done?

A SharePoint Publishing site can also be configured to make use of the ASP.NET output cache to store rendered ASPX pages in memory. You can only make use of this cache when the P**ublishing features are activated on your site collection. This means that only publishing pages can be cached.

User must be a site collection administrator or have full control within web application policy to modify this settings.

Here is code to disable it:

Param($Url)

[System.Reflection.Assembly]::LoadWithPartialName(“Microsoft.SharePoint.Publishing”)
$cacheSettings = new-object Microsoft.SharePoint.Publishing.SiteCacheSettingsWriter($Url); 
$cacheSettings.EnableCache = $true; 
$cacheSettings.Update();

Save the file as DisableOutputCache.ps1 and run like this

powershell "& ./DisableOutputCache.ps1 -Url http://dev-moss.com"
