Description

Flushes currently available output to the client. During each page request the generated output is stored in a buffer until the page is completely processed. Calling the <cfflush> tag will flush the current contents of the buffer. NOTE: After calling the <cfflush> tag you will not longer be able to call some tags that modify the buffer (ex: cflocation, cfhtmlhead).
