Apache - Maintenance Page
- Activate/Deactivate with a file.
- Bypass with a custom request header.
With the following Apache Rewrite rule, temporarily redirect all traffic to a maintenance page when a file named
maintenance exists at the same level as the DocumentRoot directory. i.e. if your DocumentRoot is
/var/www/public_html/ then creating the file
/var/www/maintenance would trigger Maintenance mode.
Use something like the ModHeader Chrome browser extension to bypass the maintenance page by setting a
X-Maintenance request header with a value of
tF0BOCn4z8HgG2Kw (replace this with your own unique passcode string).
