I have Magento running with Varnish in front of it on port 80, the whole site works great, except on the category view. Their are two prices per product, that are generated by a custom module, they are being loaded as the same for every product in that category as the first item in the category. example here http://tinyurl.com/bthd9rn It should be straightforward to resolve as I am using a community magento extension http://www.magentocommerce.com/magento-connect/made-cache-9281.html that is controlling the caching. The resolution must not impact the current page load times.
