使用 InternetGetCookie 获取 Session Cookie

[jiazhigang]

"InternetGetCookie also searches memory for any session cookies, that is, cookies that do not have an expiration date that were created in the same process by InternetSetCookie, because these cookies are not written to any files. "

意思是说如果要获取 session cookies 必须是在同一个进程内用 InternetSetCookie 方法创建的 session cookies 才能获取到，如果是 Web服务器设置的 Session Cookie 又如何获取呢？
