删除cookie失败
我面临着 cookie 的大问题。
我的域名是 abc.com
在我第一次登录 facebook connect 时，facebook 在我的计算机上创建了一个 cookie，
cookie name fbs_12345
cookie value gdgdfgdf
cookie host: abc.com
然后在我从 facebook connect 注销后。 此时，我尝试通过设置 cookie date- 10 来删除 cookie，但失败了，唯一成功的是将 cookie 值设置为“”
然后我再次通过 facebook 连接重新登录，facebook 在我的计算机上创建了另一个 cookie 此时
cookie name fbs_12345
cookie value gdgdfgdf
cookie host: .abc.com (with a dot in front)
，我无法访问cookie 不再存在，显然这是由于 cookie 主机造成的，一个没有前缀点，一个有前缀点
如果我删除其中一个 cookie，则会显示另一个 cookie 值。
有什么办法可以干净地删除第一个 cookie？
……
Function printCookie
dim x,y
for each x in Request.Cookies
response.write("<h3>")
if Request.Cookies(x).HasKeys then
for each y in Request.Cookies(x)
response.write(x & ":" & y & "=" & Request.Cookies(x)(y))
response.write("<br />")
next
else
Response.Write(x & "=" & Request.Cookies(x) & "<br />")
end if
response.write "</h3>"
next
End function
I am facing a big issue with cookie.
My domain is abc.com
At the first time I login to facebook connect, facebook created a cookie at my computer as
cookie name fbs_12345
cookie value gdgdfgdf
cookie host: abc.com
Then after I logout from facebook connect.
At this point I try to delete cookie by setting cookie date- 10 but fail, the only success is set cookie value to ""
Then I relogin via facebook connect again, facebook created another cookie at my computer as
cookie name fbs_12345
cookie value gdgdfgdf
cookie host: .abc.com (with a dot in front)
At this point, I cannot access the cookie anymore, apparently it is due to cookie host, one without prefix dot, one with prefix dot
If I delete one of the cookie, then another cookie values will show out.
Any way to do a clean removal of first cookie?
.....
Function printCookie
dim x,y
for each x in Request.Cookies
response.write("<h3>")
if Request.Cookies(x).HasKeys then
for each y in Request.Cookies(x)
response.write(x & ":" & y & "=" & Request.Cookies(x)(y))
response.write("<br />")
next
else
Response.Write(x & "=" & Request.Cookies(x) & "<br />")
end if
response.write "</h3>"
next
End function

我终于找到了在我的电脑上彻底删除 facebook 创建的 cookie 的解决方案。
经测试可与 chrome、firefox、IE8 配合使用。
对于我的情况，设置cookie过期是行不通的。
对我有用的解决方案：
在 ASP classic 中将 cookie 值设置为空并将 cookie 主机设置为其他域。
执行此操作后，这个特定的 cookie 将消失。
Response.Cookies("fbs_" & FACEBOOK_APP_ID) = ""
Response.Cookies("fbs_" & FACEBOOK_APP_ID).Domain = "anyotherdomain.com"
我相信如果用php编写代码，会更简单，
感谢这篇文章给出的 cookie 删除想法：
删除用户注销时我的应用程序中的 facebook 会话 cookie
I finally found the solution to do clean removal of cookie created by facebook at my computer.
Tested to work with chrome, firefox, IE8.
For my situation, set cookie to expire is not working.
The solution that works for me:
In ASP classic set cookie value to empty and cookie host to other domain.
After doing this, this particular cookie will gone.
Response.Cookies("fbs_" & FACEBOOK_APP_ID) = ""
Response.Cookies("fbs_" & FACEBOOK_APP_ID).Domain = "anyotherdomain.com"
I believe if code in php, it will be simpler,
Thanks to the cookie deletion idea given by this post:
