Name
CFFLUSH — New in ColdFusion 5.0
Synopsis
<CFFLUSH>
Flushes all currently available content to the client.
CFFLUSH is typically used within loops or output
queries to send results back to the client in incremental chunks. The
first time a CFFLUSH tag is encountered on a page,
it sends all the HTTP headers for the request along with any
generated content up to the position in the template where the tag is
encountered. Successive CFFLUSH tags return any
content generated since the previous flush. Once a
CFFLUSH tag has been used in a template, you
can’t use any other CFML tags that write to the HTTP header;
doing so causes ColdFusion to throw an error because the header has
already been sent to the browser. These tags include
CFCONTENT, CFCOOKIE,
CFFORM, CFHEADER, and
CFHTMLHEAD. In addition, attempting to set a
variable in the cookie scope with the CFSET tag
results in an error because cookies are passed from the server to the
browser in the HTTP header.
Attribute
-
INTERVAL="integer" The minimum number of bytes that should be returned by the server before the output buffer is flushed. Optional.
