新的欧盟 Cookie 法 - 我如何知道人们是否选择退出？
根据新的欧盟法律，我必须要求我的用户选择在他们的计算机上安装 cookie。
因此，每次我想设置 cookie 时，我都必须查看用户是否选择加入，如果没有，我就不应该设置 cookie。
当他们访问该网站时，会弹出一个窗口，询问他们是否愿意选择加入。如果他们单击“否”，我无法在他们的计算机上放置 cookie 来表明他们已单击“否”。当他们浏览网站时，我怎么知道他们点击了“否”？
我只需要在他们访问的每个页面上显示弹出窗口吗？或者将其存储在会话变量中？ （根据新法律，使用会话仍然可以吗？我假设 cookie 是使用会话密钥设置的？）。
谢谢
According to new EU laws I have to ask my users to opt into having cookies installed on their computers.
So every time I want to set a cookie I have to see if the user has opted in and if they haven't I shouldn't set the cookie.
When they come to the website a popup will ask if they want to opt in. Should they click "no" I cannot put a cookie on their computer to say they've clicked no. How do I then know, as they go through the website, that they've clicked "no"?
Do I just have to show the popup every page they go to? Or store it in a session variable? (is using sessions still ok under the new law? I assume a cookie is set with the session key?).
Thanks

我不是律师，但我最近一直在阅读这方面的内容，很明显，根据新规定，并非每个 cookie 都被认为是平等的，并且不需要对所有 cookie 都进行选择。
这些法规最热衷于确保允许跟踪网站之间的用户操作/数据的 Cookie 必须选择加入，而在另一个极端，则选择不包含个人信息的 Cookie，例如仅用于某个特定网站的安全（如会话 cookie）可能根本不需要许可。
英国 ICO 网站有一些非常清晰的页面和信息。 PDF（包括：http://www.ico.gov.uk/for_organizations/privacy_and_electronic_communications.aspx）关于这个主题，绝对值得一游。
I'm not a lawyer but I've been reading up on this recently and it is quite clear under the new regulations not every cookie is considered equal and opting in is not required for all of them.
The regulations are most keen on ensuring that cookies that allow tracking of users actions/data between websites must have an opt in, at the other extreme, cookies that contain no personal information and are, for example, only used for security on one particular site (like a session cookie) may not need permission at all.
The UK ICO website has some very clear pages & PDFs (including: http://www.ico.gov.uk/for_organisations/privacy_and_electronic_communications.aspx) on the subject and is definitely worthwhile visiting.
