如果移动网站中不存在文件，如何将用户重定向到桌面网站？

Question

I have created a www.example.com and m.example.com. The m.example.com resides inside the htdocs/m/ folder. I am using the below codes in the .htaccess:

# Redirect external .php requests to extensionless url
RewriteCond %{THE_REQUEST} \s/+(.*?/)?(?:index)?(.*?)\.php[\s?] [NC]
RewriteRule ^ /%1%2 [R=302,L,NE]

#mobile
RewriteCond %{HTTP_HOST} ^m\.example\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/m(/|$) [NC]
RewriteRule ^(.*)$ m/$1 [L]

# Resolve .php file for extension-less php urls
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/$1\.php -f [NC]
RewriteRule ^(.+?)/?$ /$1.php [L]

Now,if users hit m.example.com/abc and if the abc files doesn’t exist, it will redirect users to the error page, as I have the below code on the .htaccess code inside the htdocs/m/ folder

ErrorDocument 404 http://m.example.com/error

But now I want the users to be redirected to www.example.com/abc instead, as abc may be a valid file in the desktop version. Only if the files also doesn't exist in the desktop site, the users will be redirected to the error page.

You can place this rule as first rule in DocumentRoot of m.example.com:

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME}\.php !-f
RewriteRule ^(.+)$ http://www.example.com/$1 [L,R=302]
