Apache MOD_HEADERS，将以下内容添加到根目录.htaccess文件

Apache MOD_HEADERS, add the following to your root .htaccess file

<FilesMatch "\.(php|cgi|pl|htm)$">
    Header set X-UA-Compatible IE=EmulateIE8
</FilesMatch>

这将在所有php，html，perl和cgi文件的http标头中设置该标头，但是我对x-ua标头有过非常糟糕的体验，并发现它并不总是有效。

This will set that header in the http header of all php, html, perl and cgi files, but I have had very bad experiences with the x-ua header, and found that it doesn't always work.
