[wp-hackers] Getting the entire HTML page generated from WordPress

[zhaiziming at gmail.com]

Don't buffer your whole page, it is not a good idea for page response 
time. Instead, in your template file, use ob_start("your filter 
function") and ob_end_flush() to filter the_header(), the_content(), 
the_sidebar(), and the_footer() separately.
Or if you really want to do a whole page filter. template_redirect is 
the best hook to start the buffer, and use php function 
register_shutdown_function() to flush the buffer.
