JotCache 5.0.1 released

After two release candidates stable JotCache ver.5.0.1 is now available on download area. Major new features against ver.4. are presented in article JotCache 5.0.RC with memcached storage and other new features.

JotCache ver.4.2.2 used with Virtuemart 2 currency selection

currency-select2JotCache is often used on Virtuemart shopping sites with good results for much faster page responses. But in cases when shop was configured to run with different currencies until present time was not possible to use any page caching.

The reason behind problematic behavior with page caching is usage the same URL for pages (product categories or product details) with different page content caused with currency presentation and recalculation. In case of active page caching  the first page content with some currency was stored into cache. All later requests to the page returned not actually set currency but currency from first cached content.

jotcache-plugin-setting-session-varsIn Virtuemart 2 actual set currency for each visitor is stored as session variable 'virtuemart_currency_id'. JotCache ver.4.2 can distinguish the value of session variable and to store different page content in cache storage. JotCache system plugin has new parameter ' Session Variables Split' which is used for described purpose.

jotcache-options-session-vars2After proper setting of session variable can be seen product pages cached with different value of session variable in JotCache Management View table. For better overview can be set in component options parameter 'Show session data'.

JotCache 5.0.RC with memcached storage and other new features

Development of JotCache reacts on requirements comming from forum discussions and practical experience with  thousands of Joomla web sites. Newest developed major version of JotCache is ver.5.0 primarily prepared for Joomla 3.3. New features covers following areas :

  • Multisite operation
  • Use of memcached (server) as cache storage
  • Extended URL caching rules (include/exclude general mode, using logical AND in rule expressions)
  • Cache Operation Modes (previous Browser Split) with possibility for each browser category (incl. phones, tablets) to select own operation mode - exclude from caching, use common cache (for different browser categories) or use individual cache

Now look on memcached server used as JotCache cache storage. General meaning about using different storages for caching can be expressed as :

Local disk caching is faster than using a local memcached (due to communication performed via TCP/IP protocol), and much faster than using a remote memcached server (TCP/IP connections with network latency).

Memcached storage for JotCache requires :

    Memcached server (service on Windows) which usually listening on port 11211
    PHP module memcache (lighter, oldier solution) or PHP module memcached (newer solution)

Memcached settings in JotCache are independent from global cache setting in Joomla and they are defined on storage tab of JotCache plugin edit form :

 jotcache-plugin-memcache-params

JotCache 4.1 for Joomla 3.2 - what is new

JotCache ver. 4.0 scope of functionality (new plugins for site crawling and recaching of selected scope of pages, enhaced module caching exclusion based on template position, separation of cached pages depending on active cookies) which was first time included in JotCache for Joomla 2.5 is now available in download area also for latest Joomla 3.2.2 version.

Additional was full rewritten JotMarker plugin code because all previous versions does not have satisfactory results by using module exclusions. Despite of the tries to improve module exclusion from caching in JotCache ver.3.2.3, 4.0.3. and 4.0.5 for Joomla 2.5 was not possible on some sites to adjust this function for proper operation. Most of popular template engines are not using core template structure of Joomla and deriving compulsory parameters (mainly 'style' parameter) needed for template position exclusion in JotCache was hard to solve task. New solution in ver.4.1 requires only to set selection of template positions for module exclusion and all other parameters are internal derived from Joomla core. This dependability on Joomla core code requires carefull preparation of upgrades (Joomla itself as well as JotCache coming versions) for smooth operation of the site under new conditions. When installing JotCache look on verified versions of Joomla suitable for correct operation.

Detail description of new JotCache version is available on Help pages.
