Hi Rodney,
With apsb13-27 use section 2 for 9.0.1.
You would also do well to apply apsb13-19.
CHF4 includes 1 2 3.
After CHF4 + apsb13-19 + apsb13-27 you will have these JARs in ColdFusion9\lib\updates
chf9010004.jar
hf901-00011.jar
After CHF4 you might like to be aware this implements a new setting in ColdFusion, Post Parameter Limit. Read more about that here:

HTH, Carl.
