基本上就是http://avitel-bg.com/xdocs/MCACC.pdf
当我打开它时，我被重定向到xdocs(根)的父文件夹，我无法查看文件。如果我打开链接www (http://www.avitel-bg.com/xdocs/MCACC.pdf)，我可以正常查看PDF。
这是我的htaccess: Options +Indexes +FollowSymLinks -MultiViews

问题在于你的重定向目标，因为它将所有非www请求重定向到根
如果你想把非www的请求重定向到子文件夹，把你的最后一条规则改成:
RewriteEngine on
rewritecond %{http_host} ^avitel-bg.com [nc]
rewriterule ^(.*)$ http://www.avitel-bg.com/xdocs/$1 [r=301,nc,l]
