security - &sa=U&ei 是什么意思？

Question

我有一个网站，今天查看日志，我发现我的服务器对页面的一些请求附加了此变量&sa=U&ei。

你们能告诉我 &sa=U&e 是什么意思吗？可能是寻找可空票据的尝试吗？可能是安全威胁吗？

&sa=U&ei=XuRBT92UFseYhQf_w7HeBQ&ved=0CNYBEBYwYw&sig2=Rt1Cr_FCPD1-6VYu__Oavg&usg=AFQjCNFlHVaDQL--kgDbOn2vNgUqwUOsTA

我的日志中的错误是:

A potentially dangerous Request.Path value was detected from the client (&)

But nevermind. I found the offending culprit. Seems that for some reason my "GoogleEnhancer" became "incompatible" with Firefox. It worked fine even before I updated to 10, but go figure. And it wasn't the whole add-on, it was the "Use Google Classic" radio button turned on. I got this add-on after Google started making their search engine so... oh, what's the word I'm looking for... umm... oh, yeah... crappy!

I figured out what it is... I have an add-on called google enhancer which obviously hasn't been updated properly of late. Disabled it and it worked fine. Well that was a waste of a thread. Thanks for the help though guys.

因此，请求中不必要的部分是由过时的 Firefox 插件创建的，没什么严重的。使用该附加组件的访问者遇到的问题比您的网站还多:)
