Cache homepage only?

Anyone?

Well normally it’s done the other way around, people don’t want the homepage cache, rather just the rest. There’s an option available for that. However, in your case…

Depending on how large your website is, you could simply tell it what pages or URL folder structures not to cache?

Under the Page Cache options, there’s a ‘Never cache the following pages’ in which you could throw all the pages you don’t want cached.

For example (you can use the .* for all), normally it would be just selected areas:

/checkout/.*
/cart/.*
/order/.*
/members/.*

In the page cache settings you have the option to cache posts make sure to uncheck that option and then it should be fine.
