Recommended cache settings in html meta tags plugin

NaturalEnquirer

I am using the html meta tags plugin, mainly for the description and keywords.

It also has cache settings and was wondering if there are any recommended settings for ZenPhoto gallery pages.

Per Google: "The http-equiv values pragma and expires are ... probably unnecessary uses; any scenario where there is a legitimate reason to limit caching, the author is going to have enough control over the server to send the appropriate headers. In addition, the meta tags can't be considered reliable (e.g. proxies and transparent caches aren't going to honour them)."

I'm not sure how to set these:

cache-control
expires
pragma - I've set this to cache

Any recommendations? If it matters, I'm using zpGallerific theme.

Thank you.

Generally most of the html meta tags are not really important at all anymore as Google's info says. Actually only the description has still some real value.

The cache one is to my knowledge actually for telling the browser not to used its cache but get the pages directly from the website's server.

Probably you can skip the other two.
