We have asolution in place where we health check the HTTP servers looking for a specific page on the server and expect a 200. We probe the servers with a string like this GET /health.aspx HTTP/1.1\nHost: defaulthost.my.company.org \nConnection: close\n\n servers normally respond with 200 when healthy. When the servers teams need to do server maintenance they change that page to return a different response code like 600 and that will let F5 fail the server out of the pool for maint. When they are done they restore the original response code 200 and F5 will place the server back into rotation in the pool.
