This lets you set aside a section of your computer's hard disk to store representations that you've seen, just for you. The browser cache works according to fairly simple rules. It will check to make sure that the representations are fresh, usually once a session (that is, the once in the current invocation of the browser).

output_start_filename, output_start_lineno);
} else {

e_session_name = php_url_encode(PS(session_name), strlen(PS(session_name)), NULL);
