一 这是一个IE8BUG问题:

 

Internet Explorer has a number of features designed to render pages more quickly. One of these features is called the "Lookahead Downloader" and it's used to quickly scan the page as it comes in, looking for the URLs of resources which will be needed later in the rendering of the page (specifically, JavaScript files). The lookahead downloader runs ahead of the main parser and is much simpler-- its sole job is to hunt for those resource urls and get requests into the network request queue as quickly as possible. These download requests are called "speculative downloads" because it is not known whether the resources will actually be needed by the time that the main parser reaches the tags containing the URLs. For instance, inline JavaScript runs during the main rendering phase, and such script could (in theory) actually remove the tags which triggered the speculative downloads in the first place. However, this "speculative miss" corner case isn't often encountered, and even if it happens, it's basically harmless, as the speculative request will result in downloading a file which is never used.


二 解决:
   在base href中使用绝对的URL 址址。

<base href="http://sxx.com/" />
