HAProxy Maintenance Page
| # | |
| # Proof of concept for a HAProxy maintenance mode | |
| # | |
| # | |
| # Control the maintenance page during runtime using the stats socket: | |
| # | |
| # To put the whole site in maintenance mode (for all IPs): | |
| # > add acl #0 0.0.0.0/0 | |
| # | |
| # To exclude your own ip, so you are able to test things out: | |
| # > add acl #1 8.8.8.8 | |
| # | |
| # To exit maintenance mode again simply remove the mask from #0 again: | |
| # > del acl #0 0.0.0.0/0 | |

Just saying, there is a typo here, the backend is called "web_maintenEnce", but the use_backend directive references "web_maintenAnce".
