I have a component which has a feed. This feed updates constantly, pulling information from external sources. To reduce pressure on my server at high traffic periods, I want to give the generated feed a cache of around 10 seconds, possibly less.
However, as far as I am aware, Joomla's cache time is global across all components and has a minimum time of a minute, even though modules will work in seconds and can be added on a module-by-module basis.
Is there any way to make a component view have a shorter cache time than this?
The only way I can think of is a cron job that deletes the cached files, which doesn't seem an ideal approach.
