Page cache/optimisation

Page: Settings >> General settings >> Page cache
This function controls the speed at which certain pages are displayed.
The pages that your customers see contain both static and dynamic content. Dynamic content is data and information that is read from the database and inserted into the page just before the Web page is displayed. This ensures that the values are up-to-date. This includes data about prices, amounts, and so on.
Updating and creating the page takes time. The display rate of the page is therefore dependant on the proportion of the content which has to be updated.
Pages where the content does not change can be cached and displayed more quickly.
Your customers expect up-to-date pages with fast loading times. For this reason, it is a good idea to find the optimum setting between displaying current content and quicker availability of the page.
The page cache allows you to configure how often certain pages are updated. When deciding this, bear in mind how often you change and update the data on these pages.
For example, if you change the prices of your products weekly, pages which display prices need only be updated every week after the price change. During the rest of the week, these pages can be loaded and displayed from the cache.
The same applies for stock data. When inventory levels of products are evaluated for display in the shop, the page cache must be set so that when the stock level changes during the order process, the corresponding pages are updated. For more about this, see Inventory, below.
The status of the page cache is displayed in the Administrator menu; see Administration navigation, above.
Use the check box Activate page cache... to switch the page cache function on or off.
Once you have switched the page cache on, select your preferred update intervals for the pages listed on the screen. Save your entries by clicking Save.
If you have made extensive changes to data and information, you can update all the pages with one click. To do this, click Update immediately.
Note: If you make changes while in the administration area and these changes are not immediately visible on the Web site, check the setting for the period of validity. If necessary, click Update immediately.
Remember the following:
We recommend that while setting up the Web site you disable the page cache option in order to apply frequent changes immediately. When your shop goes into Live operation, click the check box and set the longest possible periods of validity.
