我对 mod-rewrite 的东西确实很陌生。
注意：- 这里的 URL 是通用的，并且所有文件夹和子文件夹都在同一主机上。
用户用于访问其页面的 URL 是http://myurl.com/1234/filename.jpg
此处子文件夹的名称是一个整数，是唯一的，由另一个应用程序动态生成。
子文件夹存储特定于个人用户的图像。
因此文件夹结构如下
main1 = document root
main2 is another folder within main1 or document root.
/main1/1234/filename.jpg
/main1/5678/filename.jpg
/main1/2345/filename.jpg
/main1/1212/filename.jpg
/main1/main2/2367/filename.jpg
/main1/main2/8790/filename.jpg
/main1/main2/9966/filename.jpg
因此，我想编写一个重写规则，以便当用户尝试输入
http://myurl.com/1234/filename.jpg,
重写规则将需要查找文件的位置并响应请求；因此对于请求 http:/myurl.com/1234/filename.jpg，实际页面位于 /main1/1234/filename.jpg，然后需要从该文件夹提供该页面。
因此，如果另一个用户发出请求http://myurl.com/9966/filename.jpg，它应该从以下目标 /main1/main2/9966/filename.jpg 提供页面
如果问题仍不清楚，请告诉我。
这是我目前所做的但根本没有任何效果。
RewriteCond {DOCUMENT_ROOT}/%{REQUEST_FILENAME} -f
RewriteRule ^(.*)$ {DOCUMENT_ROOT}/$1 [L]
RewriteCond {DOCUMENT_ROOT}/main2/%{REQUEST_FILENAME} -f
RewriteRule ^(.*)$ {DOCUMENT_ROOT}/main2/$1 [L]
非常感谢您的帮助
编辑@ShaneMadden 请查看详细信息该配置位于 .htaccess 文件中；请查找 .htaccess 详细信息
RewriteEngine on
RewriteCond %{REQUEST_URI} ^/main1/\/.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(main1)(/\/.+)$ $1/main2/\$2

答案1
你几乎成功了！！
您忘记了“％”！！
并且单独使用与应该起作用的操作^(.*)$相同：(.*)
RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} -f
RewriteRule (.*) %{DOCUMENT_ROOT}/$1 [L]
RewriteCond %{DOCUMENT_ROOT}/main2/%{REQUEST_FILENAME} -f
RewriteRule (.*) %{DOCUMENT_ROOT}/main2/$1 [L]
如果它有效请告诉我；）
