How to Delete a Cookie?
Hello - I managed to get a cookie set. Now I want to delete it but it is not working. Do I need to do another 'set-cookie' in the HTTP header? I tried (code below setting expires to 0) and it didn't work. c = Cookie.SimpleCookie(os.environ[HTTP_COOKIE]) c[mycook][expires] = 0 print c In case its useful, here is how I set my cookie: c = Cookie.SimpleCookie() c[mycook] = Tryg c[mycook][expires] = 60*60*24 c[mycook][comment] = c[mycook][path]= / c[mycook][domain] = c[mycook][secure] = print c Thanks Tryg -- http://mail.python.org/mailman/listinfo/python-list

Isn't it better to learn a bit of framework like Pylons and have it all done for you (e.g. in Pylons you have response.delete_cookie method)?

c[mycook][expires] = 0 Set [expires] using the following format to any time less than current (which causes the browser to delete the cookie). Here's a function I use to return a cookie expiry timestamp, negative values passed in result in cookie being deleted. def cookie_expiry_date(numdays): Returns a cookie expiry date in the required format. -ve value in = kill cookie. `expires` should be a string in the format Wdy, DD-Mon-YY HH:MM:SS GMT NOTE! Must use [expires] because earlier IE versions don't support [max-age]. from datetime import date, timedelta new = date.today() + timedelta(days = numdays) return new.strftime(%a, %d-%b-%Y 23:59:59 GMT) Usage: c[mycook][expires] = cookie_expiry_date(-10) # any negative value will remove cookie HTH, JC -- http://mail.python.org/mailman/listinfo/python-list

I tried reading in the existing cookie (b), creating a new cookie (c) with all the same values except for the expires but this did not get my cookie deleted. b = Cookie.SimpleCookie(os.environ[HTTP_COOKIE]) c = Cookie.SimpleCookie() c[cookieName] = b[cookieName].value c[cookieName][expires] = 0 c[cookieName][path]= b[cookieName][path] print c -- http://mail.python.org/mailman/listinfo/python-list

Why is this? The path specifies which directory the cookie is active. Usually the path is set to /, which means the cookie is valid throughout the entire domain, but you could set it to /mydir meaning it would only be active for pages within /mydir. So what would be the best way to do this. I tried reading in the existing cookie (b), creating a new cookie (c) with all the same values except for the expires but this did not get my cookie deleted. To kill the cookie, simply set a cookie with the same name (and path) and a past date (or 0, although IIRC there was some issue with 0 being used on a particular browser some time ago, can't remember which on at the moment) as an 'expires' parameter, is enough to tell the browser to kill an existing cookie with that same name, regardles of it's value or previous expiry, etc. Basically, when you set a cookie, the browser overwrites the previous one of the same name if it exists. If not, it creates a new cookie with your specified parameters. So in your case, when you want to kill the cookie you set previously, you should be able to just set a cookie of the exact same name, path and 'expire' it appropriately, and the browser takes care of the rest. Don't worry about assigning it's previous value, the browser is just going to delete it anyway. JC -- http://mail.python.org/mailman/listinfo/python-list
Re: How to Delete a Cookie?
To kill the cookie, simply set a cookie with the same name (and path) Actually you may not even need to specify the path. Just the name and expires param should do the trick. Haven't played with cookies in a while so try with and without the path. -- http://mail.python.org/mailman/listinfo/python-list
