如果没有找到文件/文件夹mod-rewrite目录 [英] mod rewrite directory if file/folder not found

问题描述

我有一个名为文件夹1的文件夹在我的根目录

www.domain.com/ www.domain.com/folder1

我需要重定向所有的请求www.domain.com该转起来是一个404错误，以FOLDER1。像这样：

www.domain.com/a_file.txt

如果a_file.txt不存在，在文件夹1看：

www.domain.com/folder1/a_file.txt

我想这对子目录的工作原理相同，像这样：

www.domain.com/a_folder （重定​​向如果没有根存在）

www.domain.com/folder1/a_folder

我知道我应该使用的RewriteCond％{REQUEST_FILE}！-f，但我似乎无法找到答案。

解决方案

  RewriteEngine叙述上
的RewriteBase /
的RewriteCond％{REQUEST_URI}！^ /文件夹1 /
的RewriteCond％{} REQUEST_FILENAME！-f
的RewriteCond％{} REQUEST_FILENAME！-d
重写规则（。*）文件夹1 / $ 1 [L，R]
 

• 在第一重写康德确保您不会循环（如果该文件不里面的文件夹1存在任何
• 第二个将检查目标不是一个文件
• 第三 - 它不是一个文件夹或者
• 最后，重写URL。 →标志意味着这是最后加的规则（即使有后的规则），研究表示重定向。您还可以添加 QSA 标记，如果你想传递给原来的发送到新的URL
的任何查询字符串参数

I have a folder named "folder1" in my root directory

www.domain.com/ www.domain.com/folder1

I need to redirect all the requests to www.domain.com that turn up to be a 404 error, to folder1. Like so:

www.domain.com/a_file.txt

If a_file.txt doesn't exist, look in folder1:

www.domain.com/folder1/a_file.txt

I want this to work the same for subdirectories, like so:

www.domain.com/a_folder (redirect if it doesn't exist in the root)

www.domain.com/folder1/a_folder

I know I should use RewriteCond %{REQUEST_FILE} !-f but I can't seem to figure it out.

解决方案

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !^/folder1/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) folder1/$1 [L,R]

• The first rewrite-cond ensures you do not loop (in case the file does not exist inside folder1 either
• The second one checks that target is not a file
• The third - that it is not a folder either
• And, finally, rewrite the url. L flag means this is the last rule applied (even if there are rules after it), R means redirect. You can also add QSA flag if you want any query-string parameters passed to the original be sent to the new url
