[webkit-dev] Cookies in GDK Port

Once you give the file name ,I think by default curl starts saving your
cookies as and when you receive them. So i think you need not to call
curl_easy_clenup(). I am not sure of this.

The best solution i think is disable the cookie handling in the curl.
and handle it on your own outside the webkit, Through the Cookiejar
interface. setCookie,Cookies, and cookiesEnabled functions.

if curl creates the cookie file , you will have following problems.

1) Deleting individual cookie from the Cookie list is not supported.
2) Disabling the Cookies Runtime is not supported. if you want to
achieve this you need to forcefully add the cookie header in the
request , so that curl does not add , which is a over head.
3)you will not be able to show the cookie list with the details to user.
It's not that it is not possible. but then again you need to get the
info from curl and show it......
4) you will have to maintain the list of Blocked domains outside and
handle it. so cookie handling will be at two places.
5) even i saw a bug in the curl cookie handling in GDK port.

will not come. it is due to cookies.
