Here is an example of a custom refresher:

The refresher:

/// <summary>
/// The relation cache refresher.
/// </summary>
internal class RelationCacheRefresher : JsonCacheRefresherBase<RelationCacheRefresher>
{
    /// <summary>
    /// Gets the id.
    /// </summary>
    public static Guid Id
    {
        get
        {
            return new Guid("7b8053d6-6ff4-46e2-94c0-115055a8a192");
        }
    }

    /// <summary>
    /// Gets the unique identifier.
    /// </summary>
    public override Guid UniqueIdentifier
    {
        get
        {
            return Id;
        }
    }

    /// <summary>
    /// Gets the name.
    /// </summary>
    public override string Name
    {
        get
        {
            return "Relation Cache Refresher";
        }
    }

    /// <summary>
    /// Returns the real instance of the object ('this') for use  in strongly typed events
    /// </summary>
    protected override RelationCacheRefresher Instance
    {
        get
        {
            return this;
        }
    }
}

Call the refresher:

private void ContentServiceSaved(IContentService sender, SaveEventArgs<IContent> e)
{
    DistributedCache.Instance.RefreshAll(RelationCacheRefresher.Id);
}

Execute the refresher:

RelationCacheRefresher.CacheUpdated += (sender, args) =>
{
    // Clear cache or something
};

Thanks Jeroen, I did a quick Google search on JsonCacheRefresherBase to find more information about what it is and I came across this post, where Shannon explains that there's already an event available for exactly this purpose: PageCacheRefresher.CacheUpdated.

Tried it just now and it works perfectly :-)
