MWS use persistent variables in python

[maggias]

Hi,

I was wondering if its possible to use persistent variables in a mod_python handler.

What I mean is a variable that is stored between two user requests, for example a counter that increments every time a user access the page, although that is not what I intend to do .

I tried this here:

global count

def handler(req):
	from mod_python import apache
	
	try:
		# Should be execute if variable is defined in memory 
		req.write("count: " + str(count))
		count = count + 1
	except Exception, e:
		# If variable is not bound an exception is thrown, then this is called
		count = 0
		
	req.write("count: " + str(count))
	
	return apache.OK

but it always just writes out:
count: 0

but not count: 0 after the first time, count: 0 and count: 1 after the next and count: 1 and count: 2 after the third ... as I want.

If any one knows how to do that please let me know. I want to try to use something like this for setting up an environment (reading stuff from database and stuff like that) just one time and store it in a persistent variable for fast access for subsequent requests.

Best regards,
Magnus

It seems that global variables are understood incorrectly. Here's an example how they work and how they can be used.

def handler(req):
	global count
	from mod_python import apache
	
	try:
		# Should be execute if variable is defined in memory 
		req.write("count: " + str(count))
		count = count + 1
	except NameError, e:
		# If variable is not bound an exception is thrown, then this is called
		count = 0
		
	req.write("count: " + str(count))
	
	return apache.OK

If this doesn't help please tell more details about your problems.
