How to disable umbraco cache

Question

My content editors are complaining because the content they edit is not being updated immediatly in the browser and it's making their job hard.

I have tried the following in umbracosettings.config to no avail:

<settings>
    <content>
        <XmlContentCheckForDiskChanges>true</XmlContentCheckForDiskChanges>
        <ContinouslyUpdateXmlDiskCache>True</ContinouslyUpdateXmlDiskCache>

What options do i have?

Notes:

• This site is published on Azure hosting

• I make calls from my controllers that traverse nodes like this:

  public class HomePageController : RenderMvcController
  {
      private IServices services;
  
      public HomePageController(IServices services)
      {
          this.services = services;
      }
  
      public override ActionResult Index(RenderModel model)
      {
          var viewModel = this.services.PageService.GetByID(CurrentPage.Id),
          //
          return View("~/Views/MVC/Page/Home.cshtml", viewModel);
      }
  

• and the traversing within the services on root node:

  /// <summary>
  /// The root node is required in getting content by document type.
  /// </summary>
  protected IPublishedContent RootNode {
      get
      {
          if( this.contentRootNode == null )
          {
              this.contentRootNode = this.umbracoHelper.TypedContentAtRoot().First();
          }
  
          return this.contentRootNode;
      }
  }
  
  protected IEnumerable<IPublishedContent> GetPublishedContent(string documentTypeAlias)
  {
      IEnumerable<IPublishedContent> publishedContent = this.RootNode.Descendants().Where(x => x.DocumentTypeAlias == documentTypeAlias);
  
      return publishedContent;
  }
