I agree totally with the above!. I tend to use a lot of frames and
client_side programming to reduce bandwith and improve the user
experience. To accomplish this, you need to distribute much of the
programming logic for navigation/validation and what I call
application "lubricant" or "glue" to the client.
Another technique I like to use is to combine the logic to:
present a form
validate a form
Re-present a form in error ( with a popup explaining all errors
Present the response to an Accepted form
in a separate program module/template... it is a lot easier to
delegate the entire process to a separate module, rather than
distribute it among separate modules navigated by index.cfm
There are times where you must invoke external operations (Cybercash,
CFHTTP harvesting, etc). These operations can timeout (no response)
or return an error.
When this happens, you need to retry a given number of times, then
try an alternate route.
At each of these stages, you could get another, possibly different, error.
Example from an early CyberCash/CashRegister implementation:
Attempt 1: Cybercash - Authorization Times out (No response)
Attempt 2: Cybercash - Authorization declined - already posted
Attempt 3: CFHTTP CashRegister - Request Posted Item Info Times out
Attempt 4: .......
To try to do this with separate modules invoked through a an index.cfm
"traffic cop" unnecessarily complicates the process.
