使用 .htaccess 将 searchglassfilms.com 重定向至 www.searchglassfilms.com

Question

我有一个域名 searchglassfilms.com，我面临的问题是 searchglassfilms.com 没有响应。如何将所有对 searchglassfilms.com 的请求重定向到 www.searchglassfilms.com？我知道可以使用 .htaccess 来实现，但到目前为止我还没有找到解决方案。

searchglassfilms.com不管用www.searchglassfilms.com正在工作，为什么？

检查一下我做了一些事情：

    # turn mod_rewrite on
RewriteEngine on

RewriteCond %{HTTP_HOST}   ^[^.]*?\.?([^.]+\.[^.]+)$
RewriteCond %{HTTP_HOST}   !^www\.                         [NC]
RewriteRule ^(.*)$         http://www.%1/$1                [L,R=301]

RewriteCond %{HTTP_HOST} ^searchglassfilms\.com$ [NC]
RewriteRule ^(.*)$ http://www.searchglassfilms.com/$1 [R=301,L]

RewriteCond %{HTTP_HOST} ^searchglassfilms\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.searchglassfilms\.com$ 
RewriteCond %{REQUEST_URI} !^/\.well-known/acme-challenge/[0-9a-zA-Z_-]+$
RewriteCond %{REQUEST_URI} !^/\.well-known/cpanel-dcv/[0-9a-zA-Z_-]+$
RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/(?:\ Ballot169)?
RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$


# Redirect non-www to www

    Options +FollowSymLinks

    # If https send to https://www.
    RewriteCond %{HTTP_HOST} ^searchglassfilms.com$ [NC]
    RewriteCond %{HTTPS} on
RewriteCond %{REQUEST_URI} !^/\.well-known/acme-challenge/[0-9a-zA-Z_-]+$
RewriteCond %{REQUEST_URI} !^/\.well-known/cpanel-dcv/[0-9a-zA-Z_-]+$

    RewriteRule ^(.*)$ https://www.searchglassfilms.com/$1 [R=301,L]

    # If http send to http://www.
    RewriteCond %{HTTP_HOST} ^searchglassfilms.com$ [NC]
    RewriteCond %{HTTPS} off
RewriteCond %{REQUEST_URI} !^/\.well-known/acme-challenge/[0-9a-zA-Z_-]+$
RewriteCond %{REQUEST_URI} !^/\.well-known/cpanel-dcv/[0-9a-zA-Z_-]+$
RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$
    RewriteRule ^(.*)$ http://www.searchglassfilms.com/$1 [R=301,L]

有人能找出根目录中的 .htaccess 文件中出了什么问题吗？
