Disable HTML Caching in Sitecore

This post has been migrated, original date 24 May 2010 I need a quick way to disable HTML caching on a Sitecore server. I didn't want to mess around with the sites setting because I wanted something a little more generic. You might be tempted to set Caching Enabled to false.

    <!--  CACHING ENABLED
            Determines if caching should be enabled at all
            Specify 'true' to enable caching and 'false' to disable all caching
      -->
        <setting name="Caching.Enabled" value="true" />

However changing this to false will cause your site to never load! A better solution is to use the HTML Lifetime setting:

      <!--  HTML LIFETIME
            The lifetime of HTML fragments added to the cache.
            Default value: 00:00:00 (ie. eternal life)
      -->
    <setting name="Caching.HtmlLifetime" value="00:00:00" />

Change this from 00:00:00 to 00:00:01.
