Thanks for the input, Tony and everyone...keep the ideas coming.
I'm about to start working out this issue today, so the more options
I have to choose from, the better!

guess) to take over. Should be a simple IP switch from one machien to another

Thanks, i have actually tried it. i just discovered that the problem isn't
displaying the image. it is most likely that cf does not support the format of
the image in the byte array.

Hi,
I have a function that has loon worked just fine and recently stopped. It
hangs when it tries to access news.google.com using CFHTTP. Does anyone know
if something changed at google to cause this problem. My code to grab the fee

Well of course it would be done in an Application.cfm file.
I just never had to look that hard to find the appropriate
Application.cfm file before.

You can configure your load-balancers to have sticky sessions, or route

this situation. Your IP change is the cheapest and simplest. It will also

From time to time, I find in my error log errors due to undefined form
variables.
The reason being that the template was requested using method GET
instead of POST.

but there are also true visitors, even

Then I convert to Variables...

One thing though, if the values are showing up in the url then your form
itself must be using GET, otherwise they wouldn't show in the URL.
I thought it was clear in my initial post that the form was indeed

Create a required variable and use that to redirect them back to the

oh no!
swfupload is ok but has some issues and limitations and it's not jquery which
makes interacting with it a bit more difficult.
I'm making a fairly sweet uploader in jquery and ended up using uploadify as
the base uploader but I alter the source code.
As far as the original question as

I am just guessing here. But that sounds like

It is common to treat post and get data in the same way; simply, user input.
I find doing this gives you greater flexibility and clarity (my page gets
input, I do stuff with it). All frameworks that I have used have done this
and it's a real snip to do at the beginning of a request somewhere:
Hey All,
I'm trying to parse out a 65mb XML file from a customer... Don't ask...
Every time I try to hit it with XMLParse(), memory spikesfrom 500mb to 1,200
and then crashes CF
Has anyone else dealt with big XML files like this?

I'd recommend grabbing a SAX parser and using that instead of the
DOM-based stuff that CF ships with. Then you can stream the file in
and deal with it's nodes sequentially, rather than having to inflate
the whole thing into a DOM tree to manipulate. Definitely can make
the code trickier to

Is that a one-image-at-a-time processor, or will it handle
multiple images submitted at once?
Multiple images is what I'm trying to accomplish. I usually let
a user select all the images they want to upload before submitting
by letting them clone the file input.
Then, within the cfc method, I
No, your cfc method won't be able to send back multiple returns. Instead,
the flash uploader will upload the files one at a time to your CFC but your
user will have the experience of sending them all at once. You will be able
to customize progress reports as the flash object will publish
Another option is to use a zip utility to handle more than one image. This can
allow for as many files as you want. Simply upload one zipped folder and then
do a recursive loop inside of the zipped folder to grab all of the images.

There is no issues it's just not as clean. It's also harder to control the
data coming back. I just went through most all the ajax uploads and thought
You can't send back multiple returns in same method but you can just output the
data which is what the flash part is looking for and it reports it back to ajax
script as many times as you need, doesn't matter if it is once or 1000.
Or you can loop over the method and grab each return and send
What if the images have other data that go with them like descriptions?
Just as easily you could first make a temp folder with a uuid or session as the
name and dump them in there without having to zip them.
If you have more than just the picture such as a description or other data then
multi
request.data = url;
StructAppend(request.data, form);
This will work if the GET request transmits the form parameters in the
url instead, but it is not the case: the url contains no value.

After processing the form, redirect the browser (302 redirect,
cflocation) to the 'thank you, your form is submitted' page.
Good point, except many times, the input process is not finished.
There may be 4 or 5 steps of form to fill before I can say thank you.
Not really simple to pass all
Create a required variable and use that to redirect them back to the
form.
Redirect them back to the form was indeed what I intent to do.
However, testing CGI.REQUEST_METHOD NEQ post seems more logical.
