Create a cookie that lasts until the browser is closed(Session Cookie?)

I am familiar with assigning, creating开发者_C百科 cookies in Python. But I am unsure how to create a cookie that will last until the current browser session is closed(so I have a very rudimentary way of telling when the user is returning to my website).

So which cookie header do I set to make sure the cookie will expire/delete when the browser is closed in Python? Do I use the SimpleCookie object or another object for this?

This thread says I set the cookie_lifetime flag/header in PHP, but what about for python? http://bytes.com/topic/php/answers/595383-how-declare-cookie-will-destroy-after-browser-closed

Would this create a cookie that expires on closing of the browser?

cookie  = Cookie.SimpleCookie()
cookie["test"] = "MYTEST"
cookie["test"]['expires'] = 0 # or shd I set the max-age header instead?
print str(cookie) + "; httponly"

Just leave out the "expires" value altogether, i.e. don't set it to anything. See the Wikipedia entry for details:

Set-Cookie: made_write_conn=1295214458; path=/; domain=.foo.com

[...]

The second cookie made_write_conn does not have expiration date, making it a session cookie. It will be deleted after the user closes his/her browser

In Python:

In [11]: from Cookie import SimpleCookie

In [12]: c = SimpleCookie()

In [13]: c['test'] = 'MYTEST'

In [14]: print c
Set-Cookie: test=MYTEST

Mack,

Your answer looks correct to me. Setting "expires" = 0 on the Morsel object should do what you want. Have you tested it?

Looks like max-age is not supported by IE:
