# WP Super Cache and buffer flushing

 * I had the latest version of WP Super Cache installed on my WordPress site, and
   it worked fine.
 * However, I did not want WP Super Cache to cache pages for known users, so in 
   order to improve performance for pages viewed by these users, I installed WP 
   File Cache… and WP Super Cache stopped working. In other words, I found that 
   it took just as long to view pages if I was not logged in as when I was logged
   in; previously, the loading of these pages was very fast.
 * After some investigation, I realised that the problem was that I had some code
   to flush the output buffers early in order for the user to feel that the site
   was more responsive, rather than waiting for all the response to be returned 
   before sending the output to the client. It seems that WP Super Cache does not
   like this.
 * Is there any way I can achieve the early flushing of output while still having
   WP Super Cache work? Even if I could have some code which detects whether WP 
   Super Cache was active or not before attempting to flush, that would be great.
 * Thanks,
 * K

 * No, Supercache needs the buffer to do the caching. You could grab the buffer 
   and display it but don’t flush it.
