regex - 如何使用重写规则来测试 cookie 中的日期？

Question

我发现你不能在下一个 Rewrite Cond 中使用 RewriteCond 反向引用作为模式条件...

我所看到的看起来是正确的，但蒂姆在下面的评论中是正确的......当我们超过保存在 cookie 中的过期日期时，这仍然是过去的。

关于如何实际测试值(value)而不是存在的任何想法？

RewriteCond %{HTTP_COOKIE} niftyExpire=([^;\ ]+)
RewriteRule .*index.html /fake.html [E=niftyExpire:%1,C]
RewriteCond %{TIME} <{ENV:niftyExpire}
RewriteRule .*fake.html /pass.html [R,L]
RewriteRule .*index.html /fail.html [R,L]

谢谢，

好吧，事实证明您理论上可以完成这项工作。但是，让我非常清楚地强调这一点，在任何情况下都不要这样做。

相比于使用脚本，使用程序支持的RewriteMap(虽然并不总是可能的)，或者在极端情况下编译修改后的mod_rewrite，我只能想象它的性能非常糟糕，并且由于在 .htaccess 文件中使用时必须针对每个请求进行准备，这将导致不负责任的大量开销。

也就是说，为了概念验证，132 行 mod_rewrite 亵渎:

RewriteEngine On

RewriteCond %{HTTP_COOKIE} niftyExpire=([^;\ ]+) [OR]
RewriteCond fail ^(fail)$
RewriteRule index.html$ /fail.html [E=niftyExpire:%1,E=RW_TSTATUS:%1]

如果有人有更简单的方法，或者可以建议可以进一步简化的方法，我会洗耳恭听。我可能通过写这个怪物犯下了反人类罪，但至少我们现在可以说这不是不可能的。
