Parameters
cacheSetting
Optional. A symbol that specifies how often the contents of a page on the Internet
are refreshed. Possible values are
#once (default) and #always. Specifying #once tells a movie to
get a file from the Internet once and then use the file from the cache without looking for an
updated version on the Internet. Specifying
#always tells a movie to try to get an updated version
of the file each time the movie calls a URL.

Description
Function and command; sets the cache size of Director.
The
cacheSize function is valid only for movies running in Director or as projectors. This
function is not valid for movies with Shockwave content because they use the network settings of
the browser in which they run.
Parameters
newCacheSize Optional. An integer that specifies the cache size, in kilobytes.
Example
This handler checks whether the browser’s cache setting is less than 1 MB. If it is, the handler
displays an alert and sets the cache size to 1 MB:
-- Lingo syntax
on checkCache if
cacheSize()<1000 then
alert "increasing cache to 1MB"
cacheSize 1000
end if
end
