I mean, there is no way to determine whether a page has changed since the last time it was visited if you're rebuilding it every time a request comes, right? :) On the other hand, when using Smarty's caching features then we have a saved version in disk and we can compare the timestamp of the cached version with the timestamp in the If-Modified-Since HTTP header sent by the client and react accordingly...</p> <p>But yes, I do agree that it is a good feature. Specially for sites that get thousands of visits a day!</p>tag:blog.limedaley.com,2018:/isso/63/2022004-12-16T14:51:00Zjondaley<p>Conditional GET is a good thing, I have been looking into that too, to make things faster. I guess I will have to see if there is a way around it with the next version, because I probably won't want to disable that feature.</p>tag:blog.limedaley.com,2018:/isso/63/2012004-12-16T07:07:48Zoscar<p>Unfortunately it will probably be not so easy in the next version... We've added support for conditional GET headers (it's optional, but it allows to save some bandwidth since clients will not have to download the whole page if it hasn't changed) so it's important not to mess around with HTTP headers. Of course if you disable support for this feature everything will be fine :)</p>
