This is just something I wanted to share in case others fell into the same trap I did. Its not a complaint about PageBlaster, and there is no request for John to fix/change anything! I thought my e-commerce site was the perfect candidate to take advantage of PageBlaster - 99% of the pages are public and everyone sees exactly the same content on each page. So I configured PageBlaster to cache all the public pages with a cache interval of 1 day and performance went up enormously. However there was one thing I didn't think of ...... the date display at the top of every page! A fairly standard feature for a website and not something I ever gave much thought to, but since setting up caching the date shown would often be yesterday's date not today's. Also some pages would show yesterday's date and some would show today's! The source of this of course is that, with a cache interval of 1 day, yesterday's cached copy of any page might still be what is shown today. The resolution is to shorten the cache interval to a few hours. That way the worst that can happen is that only people shopping in the small hours of the morning could see the wrong date. |
