When I call php script, it take a long time like waiting until finish the process, then just show the content. How can I set it to show content immediately, no caching no waiting? I want to see the progress, output sent by the script. Thanks.
I'm not sure how you can show the content immediately without caching? What exactly are you referring to?
This has nothing to do with Apache. It's a PHP question & will depend entirely on what the script is doing.
I found out myself, just set in php.ini implicit_flush = On ; Implicit flush tells PHP to tell the output layer to flush itself ; automatically after every output block
