You cant do anything that involves modifying the content headers after a cfflush either. things like setting cookies and stuff like that either.
What I usually do is use CFFLUSH to create a loading bar so the user can see that there is some progress in the page loading. It uses some javascript and dhtml stuff but works a treat you can see an example at http://dev.domainconceptdesigns.com/htmlEditor/ in the top left window as the folders load Regards Steve Onnis -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Darren Tracey Sent: Tuesday, February 03, 2004 10:49 AM To: CFAussie Mailing List Subject: [cfaussie] RE: cfflush inside cfloop What you're looking for is for the user to know that something is happening while the page is finishing, and not just have a blank white page while the whole page is being processed So stick a CFFLUSH after any headings are output, this will get the ball rolling. Also remember that most browsers will not render a table until all of the table has been received, so there is not much point doing a CFFLUSH between table rows unless you also close the table and then reopen it. Specifying column widths will help (mostly) keep that table columns lined up if you do this. I've done this to a particularly long slow page output that was frustrating users. The overall processing time was no different, but the perceived waiting time was , much smaller because _something_ is changing on the screen, even if its just the titles appearing, then the first page or so of results will keep them happy while the rest are slowly trickling out. This makes for much happier users. To answer your original question, there should be no problems with CFFLUSH in a CFLOOP. 2 things to remember anytime you use a cfflush though: 1. You can't do a CFLOCATION anytime after you use a CFLUSH. 2. You can't use any CFFORM tags after you use a CFLUSH. Not that I'm advocating CFFORM tags. Personally, I think they're evil, but apparently they write stuff into the top of the page (all that crappy javascript they use) and this can't be done if the top of the page has already been sent down to the user. CFFLUSH is your friend.
