htaccess重定向到维护文件

Question

I have an htaccess in the public directory:

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On

    RewriteBase /sub/web1/

    # Redirect Trailing Slashes...
    RewriteRule ^(.*)/$ /$1 [L,R=301]

    # HERE I NEED SOM MAGICAL ONELINER TO REDIRECT STUFF TO MAINTENANCE.HTML
    # BUT NO IDEA HOW TO WRITE IT ;(

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]
</IfModule>

and I want to add some rule inside, so when I uncomment the rule, all links that hit http://example.com/sub/web1/ or any files down that line, will be redirected to http://example.com/sub/web1/maintenance.html

I have tried to add: DirectoryIndex maintenance.html but this only redirects http://example.com/sub/web1/, if I have some subfolder or specific files like http://example.com/sub/web1/posts, it is useless.

Is there some oneliner that can even pull the domain name so it hasn't have to be typed absolutely? So, the example.com - or whatever domain - is not needed to type in the rule?

Answer 1

You can have a rule like this:

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On
    RewriteBase /sub/web1/

    # uncomment line below to route everything to maintenance.html
    # RewriteRule !^maintenance\.html$ maintenance.html [L,NC]

    # Redirect Trailing Slashes...
    RewriteRule ^(.*)/$ /$1 [L,R=301]

    # HERE I NEED SOM MAGICAL ONELINER TO REDIRECT STUFF TO MAINTENANCE.HTML
    # BUT NO IDEA HOW TO WRITE IT ;(

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]
</IfModule>
