Cookie: Not understanding again

[mosscliffe]

I have the following code, which I thought would create a cookie, if
one did not exist and on the html form being sent to the server, it
would be availabe for interrogation, when the script is run a second
time.

It seems to me there is something basic missing in that I should need
to tell the server I am sending a cookie, but all the docs I have read
imply it is done automatically, if one creates a 'Cookie.SimpleCookie'

I know my understanding is poor of web server logic, but if anyone can
help, I will be most grateful.

This may be more to do with Web Server behaviour than python
programming, but surely there is a way of doing this in python.

		c['mysession'].value += 1
		print "<HR>"
		return c
	else:
		c['mysession'] = 45
		print "No Cookie Found so setting an initial value for a Cookie", c
