Maintenance Page iRule

Dear Team,

Also note that whenever the user want to access the www.test.com and all the subsequent requests i.e "/*" need to be redirected to maintenance page.

Thank you!

The suggested sample is detailed at the URL Nitass has already posted.

[root@ve10:Active] config  b virtual bar80 list
virtual bar80 {
   snat automap
   pool foo
   destination 172.28.19.252:80
   ip protocol 6
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
[root@ve10:Active] config  b rule myrule list
rule myrule {
   when RULE_INIT {
  set static::maint_page "Sorry! This site is down for maintenance."
}
when HTTP_REQUEST {
  set maint_prefix "/maintenance.html"

  if { [HTTP::uri] equals "$maint_prefix" } {
    HTTP::respond 200 content $static::maint_page "Content-Type" "text/html" "Connection" "Close"
    return
  }

  if { [active_members [LB::server pool]] < 1 } {
    HTTP::redirect $maint_prefix
  }
}
}

 pool is down

[root@ve10:Active] config  b pool foo|grep -i pool\ member
+-> POOL MEMBER foo/200.200.200.101:80   inactive,down

 bigip responds maintenance page instead

[root@ve10:Active] config  curl -iL http://172.28.19.252
HTTP/1.0 302 Found
Location: /maintenance.html
Server: BigIP
Connection: Keep-Alive
Content-Length: 0

HTTP/1.0 200 OK
Content-Type: text/html
Server: BigIP
Connection: close
Content-Length: 80

Sorry! This site is down for maintenance.

if { [active_members [LB::server pool]] < 1 } {
    HTTP::redirect $maint_prefix
  }
