|Cache on Joomla! 1.5 : use it or not?|
|Saturday, 16 May 2009 08:44|
Here's a dilemma that afflicts every Joomler who knows what the cache: use it or not?. Before we see the clarity on this term, then look at where, how and when to activate. A cache (pronounced chesc) is a mechanism by which we offer a web page previously developed / visited (technically in cache or cache) to a visitor rather than let them develop all the code that forms the same page.
Final point: When that page you will be required (a new visitor) script caching prepared to offer visitors the saved HTML page rather than provide all the code (HTML - PHP - SQL) to process.
The result is that the new page will load in less time than the latter that we start to get.
A great advantage? Maybe!
The cache is temporary: that every tot minutes the cached pages are removed from our space. Why? Because in the meantime if the page was updated the script caching not found it goes to reprocess the page, and not finding updated offering visitors the old page.
But if you have a site already very light and waterborne clear the cache completely useless.
To activate the cache, we must, from the administrative panel, go to Site -> Configuration -> System on the right side of the screen find the settings to enable and configure the internal cache of Joomla! 1.5.
Usually you can include or exclude certain extensions from the cache at will, regardless of whether or not after that Global is the case of - usually - most of the many modules and components (such as Joom! Fish 2.0).
