Based on positive response to JotCache page caching solution from administrators of larger business oriented Joomla web sites were new features included in JotCache plugin ver.1.3 :

  • Browser split – many Joomla templates systems are using separate templates for different browser types (mostly Internet Explorer). With splitted cache storage space for different browser types you can avoid unacceptable mixing of unproper templates to site users (cached page content is not rendered when non-expired page exists in the cache). New version of JotCache has now possibility to set different page caches based on user browser type. Standart options allows to have different caches for Internet Explorer browsers - IE6, IE7, IE8, IE9. All other browser types are using common page cache.
  • Mobile phone request exclusion - when selected then all browser requests from mobile phones are excluded from page caching. This selection is used in the case when template system has separate template(s) for mobile phone browsers. Because of great variety of mobile browsers this solution is more practicable as splitting cache space on plenty of small chunks.
  • Cache Auto Clean - function allowing regular cleaning of expired page files from the server file system during normal operation of JotCache plugin. Proper setting of auto clean function is supported with optional logging of main parameters of the clean operations.

Most of Joomla templates allows to present frontend messages to the users. One of such cases can be using <jdoc:include type="message" /> in template file, which shows
messages like "your password or username is incorrect" or " Account created". These could show on any page in the site but if that page has been viewed and caches, the user will not get the message. As its not as module position it cannot be excluded from being cached with the jot chase tags. With new JotCache plugin ver.1.2.2 is exclusion of frontend messages from page caching automatic performed.

Based on sucessfull implementations of JotCache solution together with Virtuemart here are two improvements for JotCache ver.1.2.1 :

  • Component validation script jotcache.js was reworked for corrected behavior in IE8 browser
  • Module exclusions by means of jot tags for on site template can be now assigned to template positions containing not only alphanumeric characters but also characters '-'(hyphen) , '_'(underscore).

Some remarks to JotCache usage with Virtuemart are also included into JotCache FAQ.

JotCache solution consisting from JotCache Plugin and JotCache Component for advanced cache management has been successfully approved during last month on many heavy loaded websites (see also JotCache used on selected sites list). During implementation of oldier versions of JotCache were found as limitation that some non-standart implemented Joomla component or templates were not possible to proper adjust for smooth operation either using other URL query string parameters (not 'view' but e.g. 'page' or 'section') or missing jdoc:module tags in templates (e.g. Yootheme solution based on Warp). 

Thanks to Curtis Nehring of Cloae Web Designs with his intention to implement JotCache for Virtuemart e-commerce Joomla component and testing capabilities it was possible to add new powerfull feature to the solution - exclusion of pages from caching based on URL query parameters. Details about this new feature you can find in JotCache Help. The results of JotCache implementation in Virtuemart are very promissing cutting download time up to 70% of previous (already JS/CSS optimized) website speed.

Implementation of caching techniques on large websites is usually not fast 'switch-on' process but good preparation and elaborate testing. JotCache Component supports start-up tasks with extended cache management. For web administrators which have intention to implement JotCache on their websites and they have some open questions here is simple saying - do not hesitate to make contact.

New combination of system plugin and management component covers tailored processing in JotCache ver.1.1 for all types of extensions : static nad dynamic modules as well as components with static content and dynamic forms. Extended marking of cached content allows fast checking of cache operation in frontend and backend (new feature for easy selecting of cached pages which needs cache reset).
