unless there's an explicit header saying the cgi has expired (which i
didn't check), I say mozilla is doing the Right Thing, while IE and NS
don't. A GET CGI is supposed to give the same output when it's
parameters are the same, so browsers are supposed to cache it's output:
from rfc 2068:
In particular, the convention has been established that the GET and
HEAD methods should never have the significance of taking an action
other than retrieval. These methods should be considered "safe." This
allows user agents to represent other methods, such as POST, PUT and
DELETE, in a special way, so that the user is made aware of the fact
that a possibly unsafe action is being requested.
and
Methods may also have the property of "idempotence" in that (aside
from error or expiration issues) the side-effects of N > 0 identical
requests is the same as for a single request. The methods GET, HEAD,
PUT and DELETE share this property.
not saying that this is strictly followed, but this is how it's supposed
to work :)
