Hello everybody,

I want the browser to cache dynamic images served directly from the database. To
do this, I need to send headers but I don't know the exact value that has to be
entered for HTTP PRAGMA and HTTP CACHE-CONTROL (are there others which control
caching?). The image has to be cached forever (or as long as the browser permits
it to be cached). Do I also have to send the HTTP EXPIRE?

Are the following ones right? Can anybody add some? Anyway, can anybody please
tell me the correct values to accomplish this task?

header("Cache-Control: cache");
header("Pragma: cache");


Thanks very much!

Yours,
Lauri
