    Umbraco 7 - Clearing Outputcache when content node is published/deleted

    Hi,

    I am using Umbraco 7.1.9 and have outputcahce enabled on some controllers. I want to know what is the best way to clear cache when a content item is published/deleted.

    I did implement this in ApplicationStarting by extending ContentService.Published but when I do that, a custom backend section that I wrote does not show up on dashboard.

    Thanks,

    Shivani

    Hi,

    It's better to hook in to the cache refresher events. This is also the only way it will ever work on a load balancend environment.

    /// <summary>
/// The boot manager.
/// </summary>
public class BootManager : ApplicationEventHandler
{
    protected override void ApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
        // hook into core cacherefresher to make sure cache get's cleared correctly when in load balanced environment
        PageCacheRefresher.CacheUpdated += (sender, args) => this.ClearCache();            
        MediaCacheRefresher.CacheUpdated += (sender, args) => this.ClearCache();
        DictionaryCacheRefresher.CacheUpdated += (sender, args) => this.ClearCache();

        base.ApplicationStarting(umbracoApplication, applicationContext);            
    }

    /// <summary>
    /// Clears the runtime cache on all servers
    /// </summary>
    private void ClearCache()
    {            
        OutputCacheManager manager = new OutputCacheManager();
        manager.RemoveItems();
    }
}

    Thanks Dave. This does not clear cache for me and my custom section still does not show still in backend. I followed this example to create custom section.

    Turns out that tree.config was not being generated properly and that is why custom tree was not showing up. Is this supposed to be auto-generated by Umbraco or explicitly defined by user?
