php header

[reebes]

i installed a php server(lunix),and found the php server would send some http header automatically:

Expires: ...
Last-Modified: ...
Cache-Control: no-cache, must-revalidate
Pragma: no-cache

so the page can not be cached by the client browser,but i don't know how to change the setup.

who can tell me how to do?thanks.

Are you running sessions? If so, I believe PHP will prevent them from being cached by default.

Try playing with the session.cache_expire, and session-cache_limiter settings

i run sessions.
and i call session_cache_limiter() before session_start().but the page could't be cached still.
