Postponing a cfhttp request
Author: Greg Luce
Short Link: http://www.houseoffusion.com/groups/cf-talk/thread.cfm/threadid:32210#161646
Why not just invoke a CFC to do the cfhttp call? That can happen
regardless of the page request that's going on. Are you on CFMX?

Hello.
I have a page on our public facing server
that has a call to a cfhttp page on our
internal LAN. The problem I am having is the delay
users are getting while this page is getting called/executed.
There is no need for the user to be delayed while this
"post process" is going on. The remote cfhttp page on my
internal LAN has some database updates and inserts.
Is there an argument that will allow the remote page on the
internal LAN to process while avoiding the delay my users are
experiencing on the public site?
I just want this page to execute after the users submits
a page.. but they do not need to wait while it executes.
Thanks,
Dave

A couple of thoughts
Does the Intranet version need to be updated as soon as the user hits
Submit?
If not, then you could store the relevant information on the server and
then have a scheduled task running which CFHTTPs the info to the
Intranet server every 15 minutes or so
That way, the user gets immediate response, and the Intranet is updated
when the server gets the chance to do it
What happens if the Intranet server's connection is down?
Using an immediate CFHTTP can be dangerous as your data might not be
transferred at all, so you'd have to express this to the user unless you
schedule it for later
If you timeout your request, it fails completely, so the user's data
never made it to the Intranet server

That sounds reasonable.. I definitely do not want the cfhttp result returned
to the page it is on, I just want it to fire "post process"... if that makes
sense.
I will try the timeout attribute, thanks.

What about the "timeout" parameter of the <cfhttp> tag? I've only used
<cfhttp> once, so by no means am I an expert, but I would think that if you
set the "timeout" value to a low number, maybe even 0, then you use a
<cftry><cfcatch> block around the <cfhttp> to trap the timeout
error and ignore it - should work.
I would defer to the more knowledgeable member of this group if I am completely
off my rocker.

<cfflush> is a tag the list helped me with recently.
It may help your problem.

Dave,
If you can use a hidden frame, try to send the form submission to the hidden
frame page and send a JS relocation to some other page in the visible frame. That
way the processing can go on in the background while the user does other
activities. Since its using a hidden frame the user may not notice whether
anything else is happening in the background.
hth,
larry
