how to set maintenance mode for entire website with htaccess

Question

i have found this code for htaccess to disable the entire website (for maintenance mode):

Options +FollowSymlinks
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !/offline.php$
RewriteRule .* /offline.php [R=307,L]

Now in my offline.php page i have a link to css and js files, like:

<link rel="stylesheet" href="include/css/error.css">
<script src="include/js/file.js"></script>

when i use the code above to set the maintenance mode, the offline.php page is loaded, but without the css and js, how can i allow the loading of these 2 files?

and i think that is useful to disable the website for everyone except my ip, in this way i can update the website, is that possibile?

Answer 1

i find out an blog that contains answer for your question please check this site

The below examples are taken from the above mentoined site.

If you don’t already have an .htaccess file in the root of your domain, create one and add the following code. If you already have an .htaccess file, add the following code in front of everything that might be in there

RewriteEngine On

# Add all the IP addresses of people that are helping in development
# and need to be able to get past the maintenance mode.
# One might call this the 'allow people list'
RewriteCond %{REMOTE_HOST} !^83\.101\.79\.62
RewriteCond %{REMOTE_HOST} !^91\.181\.207\.191

# Make sure the maintenance mode only applies to this domain
# Example: I am hosting different sites on my server
# which could be affected by these rules.
RewriteCond %{HTTP_HOST} ^nocreativity.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.nocreativity.com$

# This is the 'ignore file list'. It allows access to all
# files that are needed to display the maintenance mode page.
# Example: pages, css files, js files, images, anything.
# IMPORTANT: If you don't do this properly, visitors will end up with
# endless redirect loops in their browser.
RewriteCond %{REQUEST_URI} !/offline\.htm$
RewriteCond %{REQUEST_URI} !/css\/style\.css$
RewriteCond %{REQUEST_URI} !/images\/logo\.png$

# Rewrite whatever request is coming in to the maintenance mode page
# The R=302 tells browsers (and search engines) that this
# redirect is only temporarily.
# L stops any other rules below this from executing whenever somebody is redirected.
RewriteRule \.*$ /offline.htm [R=302,L]

Answer 2

That's a great answer but here's the code from it in case the link ever dies:

RewriteEngine On

# Add all the IP addresses of people that are helping in development
# and need to be able to get past the maintenance mode.
# One might call this the 'allow people list'
RewriteCond %{REMOTE_HOST} !^83\.101\.79\.62
RewriteCond %{REMOTE_HOST} !^91\.181\.207\.191

# Make sure the maintenance mode only applies to this domain
# Example: I am hosting different sites on my server
# which could be affected by these rules.
RewriteCond %{HTTP_HOST} ^nocreativity.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.nocreativity.com$

# This is the 'ignore file list'. It allows access to all
# files that are needed to display the maintenance mode page.
# Example: pages, css files, js files, images, anything.
# IMPORTANT: If you don't do this properly, visitors will end up with
# endless redirect loops in their browser.
RewriteCond %{REQUEST_URI} !/offline\.htm$
RewriteCond %{REQUEST_URI} !/css\/style\.css$
RewriteCond %{REQUEST_URI} !/images\/logo\.png$

# Rewrite whatever request is coming in to the maintenance mode page
# The R=302 tells browsers (and search engines) that this
# redirect is only temporarily.
# L stops any other rules below this from executing whenever somebody is redirected.
RewriteRule \.*$ /offline.htm [R=302,L]

Answer 3

Step1: create a file'.maintence' in the root directory like .htaccess

Step2: put this code in the file

  <?php $upgrading = time();?>

Step3:Save the file.then you can see the default maintance message'Briefly unavailable for scheduled maintenance. Check back in a minute.'.

If you want to have your own warning message do below:

Create a 'maintenance.php' file and placing it in your wp-content directory, wordpress uses this file to display during any forced maintenance period that you set.
