Hi Eric,
Try modifying your import like this:
import mymodule
mymodule= reload(mymodule) # Prevent caching of mymodule
See if that works. It worked for me in another context.

Subject: Re: [google-appengine] Re: how large data can i use in App Caching
and how long will it be cached?
Hi dburns,
according to
http://code.google.com/intl/en/appengine/docs/python/runtime.html#App_Caching
handler script with main() would cache itself and the global env as an
imported module
however, in my case, I have a variable defined inside a module that
would be imported (and cached) , but i would like to have that
variable be re-initialized in every requests. In particular, with this
example
### mymodule.py
counter = 0
def increment():
global counter
counter += 1
return counter
### myhandler.py
import mymodule
print "Content-Type: text/plain"
print ""
print "My number: " + str(mymodule.increment())
print "My number: " + str(mymodule.increment())
the variable "counter" is cached and subsequent requests use the
value from the previous request
but for my case, I would like to "disable" the caching and to have
"counter" being re-initialized to 0 in every request. The 1st
str(mymodule.increment()) always gives 1, and the 2nd always gives 2
any way to achieve this?

In Python at least, GAE looks for a function called main() to enable
app caching. Simply rename main() to something else.
