Sitecore > Disable html caching of a rendering

Question

I am trying to upgrade the old project(based on storefront for Sitecore 8.0) to version Sitecore 8.1(latest one at the moment). During this process I faced with a problem when I see the same products for all categories. So, for example, I select a category first time and see correct products. After that I choose any other category, but still see the same products(from the first category). These data are returned by ProductList rendering(a controller rendering) and it is not run after the first call anymore(tried to reach corresponding action in a CatalogController in debug mode). If we clear all caches(..sitecore/admin/cache.aspx) - then it works again, but only first time.

I understand that I can't disable caching for the whole site, I need to do it for this generic page(with "*" in item name) where the commerce data are shown - so for all categories and product pages. I checked this rendering in design mode and can see that all checkboxes related to cache are unchecked at the moment. Don't know what I have missed.

Thank you in advance for the help.

I believe you have caching enabled on control/sublayout defintion level which will cause to cache that rendering on every page on the site, a while ago i was able to come up with a solution to disable caching for a specific rendering/sublayout on specific pages, while keeping it caching on other pages.

I basically created a new rendering parameter template with checkbox "Cancel Cache Settings", then in my rendering definition item, I set the parameter template to the new template, if your site runs on Sitecore MVC, do the following:

Create a class called 'SetCacheability'

namespace Sitecore.SharedResources.Pipelines.Rendering
{
    public class SetCacheability : Sitecore.Mvc.Pipelines.Response.RenderRendering.SetCacheability
    {
        protected override bool IsCacheable(Sitecore.Mvc.Presentation.Rendering rendering, Sitecore.Mvc.Pipelines.Response.RenderRendering.RenderRenderingArgs args)
        {
            if (!String.IsNullOrEmpty(rendering.Parameters["Cancel Cache Settings"])
                && rendering.Parameters["Cancel Cache Settings"] == "1")
            {
                return false;
            }
            return base.IsCacheable(rendering, args);
        }
    }
}

Create the patch config file in your include folder :

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
  <sitecore>
    <pipelines>
      <mvc.renderRendering>
        <processor patch:instead="processor[@type='Sitecore.Mvc.Pipelines.Response.RenderRendering.SetCacheability, Sitecore.Mvc']"
          type="Sitecore.SharedResources.Pipelines.Rendering.SetCacheability, [YOUR ASSEMBLY NAME]"/>
      </mvc.renderRendering>
    </pipelines>
  </sitecore>
</configuration>

Here is the blog i wrote on this: http://www.sitecorecoding.com/2014/09/disabling-caching-for-rendering-on-some.html

Hope this helps

The caching settings you've disabled are located in the presentation details on the control level:

Additionally, you should ensure that caching is disabled on your sublayout (or rendering) definition (under /sitecore/Layout/Sublayouts):
