I think you can do this by using -flush as a parameter, but to be sure 
check the documentation at

Find the file in your /etc/ directory that contains the "<IfModule 
mod_fastcgi.c>" statement.  Some places to look:

with apache:

with apache2:

Look for the statement FastCgiConfig (add it if it's not there) prepend 

That should do the job, hope it helps
