当 web 应用程序进行维护时，重定向的最佳位置是什么？

Question

We have a php+mysql web application, and sometimes we need to do some taks of maintenance (like changing files in server or executing scripts to the database)

Before doing this tasks we use to edit a .htaccess file to redirect the users to a "maintenance file".

We use to redirect to

mydomain.com/maintenance.html

but we are wondering if

mydomain.com/maintenance/

or

maintenance.mydomain.com

are better options.

Is there any reason for choose one of the three (or another different) above the other options?

Answer 1

During website maintenance to prevent users accessing the hosting page, you can use the following:

RewriteEngine On

RewriteBase /

RewriteCond %{REQUEST_URI}.^/maintenance.html$

RewriteRule ^(.*)$ http://domain.com/maintenance.html [R=307,L]

to be abled to send all users to a maintenance.html page no matter which page they requested.

Answer 2

If maintenance is actually a section of your website, that is, interactive, with various pages and info about maintenance, then surely, I'd go with the option 2.

Otherwise, mydomain.com/maintenance.html is the less confusing one.
