The other day I decided that I would completely code PokéNova in Python, which would have been a great decision, if I actually half-knew how to code it. I realised that the thing I was having the most trouble with was cookies - how to set, destroy and check (the value of) them.

So, can someone please tell me how to do it? And if they are really, really nice, could they please include an example script in their post?

Also, I'd like to know how import works, and how I can make my own modules and set it up so that I can import them in my scripts.

Thanks!

import os 
import Cookie 
 
# load the cookie values provided 
ck = Cookie.Cookie(os.environ.get("HTTP_COOKIE", "")) 
 
# example getting a cookie value: 
# for example, a userid cookie might be set.. 
userid = ck["userid"].value
import os
import Cookie

# load the cookie values provided
ck = Cookie.Cookie(os.environ.get("HTTP_COOKIE", ""))

# example getting a cookie value:
# for example, a userid cookie might be set..
userid = ck["userid"].value

There is probably a way to set cookies too using the Cookie module, but I prefer using the HTTP way directly, since my templating system doesn't print stuff right away, rather after I have generated all the content (a requirement of FCGI) 

print "Set-Cookie: userid=%s; expires=%s" % (cookie_userid, cookie_expiry)
print "Set-Cookie: userid=%s; expires=%s" % (cookie_userid, cookie_expiry)

And to destroy/expire cookies (on logout for example, would the code be like this?: 

cookie_userid = false 
cookie_expiry = "-3600" 
print "Set-Cookie: userid=%s; expires=%s" % (cookie_userid, cookie_expiry)
cookie_userid = false
cookie_expiry = "-3600"
print "Set-Cookie: userid=%s; expires=%s" % (cookie_userid, cookie_expiry)
]]>

Since cookies use timestamps when you're setting them, not relative counts of seconds, an expiry time of 0 will probably work better.
