"Pragma" is the HTTP 1.0 header for doing this. Comes in handy for
backward compatibility, as it is still supported in HTTP 1.1. Pragma
is something like a generic header field which, in this case, is used
to affect cacheing behaviour.
"Cache-control" is a new HTTP 1.1 header. It is specifically aimed at,
well, you guess, controlling cacheing. It is in fact an extendable set
of headers which allows you to do all kinds of fancy things, like
setting "max-age" or "must-revalidate" etc.
It doesn't hurt to use both of them. In fact, I'd recommend you use
both of them.
