You're welcome.

Yes, not much to say about that.

Well, my way to do this.
<code>
MEMORY = "Memory"
COMMBYTES = "Committed Bytes"
memory = win32pdhutil.find_pdh_counter_localized_name(MEMORY)
commbytes = win32pdhutil.find_pdh_counter_localized_name(COMMBYTES)

path_comm = win32pdh.MakeCounterPath((None, memory, None, None, -1, 
commbytes))

base = win32pdh.OpenQuery()
count_comm = win32pdh.AddCounter(self.base, self.path_comm)

# We query a first time to initialise counter
win32pdh.CollectQueryData(self.base)

# 100 Ms of sleep to be sure getLoad won't be called too fast
time.sleep(0.1)
# Second query to fetch results
win32pdh.CollectQueryData(base)
# Get results
count_format = win32pdh.PDH_FMT_LONG

m_comm = win32pdh.GetFormattedCounterValue(count_comm, count_format)[1]

</code>

If you have an error you can see where it is more clearly.

Probably. You may have the error in IIS logs.

Well obviously it's an IIS problem. Are you sure you can access this with 
cgi ? 
What are your windows and IIS version ?
Sorry but I can't help you anymore on this...
