multiple redirect iRules on a VS

A few things to consider:

 

 

1. Are you just add the second iRule when you want the maintenance redirect? And not removing the first? If so, at the very least change the HTTP::redirect commands to an HTTP::respond 302 and see if that helps.

 

 

2. If you want [all] users to go to the maintenance page, then it sort of doesn't make sense to trigger it based on the HTTP::uri. You should consider removing the URI condition completely for the maintenance redirect.

 

 

3. Perhaps adding another iRule is not the very best approach. You could, alternatively, maintain a data group that sets or unsets maintenance mode based on the HTTP::host field:

 

 

Example data group:

 

www1.example.com := 0

 

www2.example.com := 1

 

 

iRule pseudo code:

 

when HTTP_REQUEST {

 

if { ( [class match [string tolower [HTTP::host]] equals host_group] ) and ( [class match -value [string tolower [HTTP::host] equals host_group] equals 1 ) } {

 

HTTP::respond 302 Location "maintenance page URI"

 

} elseif { [HTTP::uri] equals "/" } {

 

HTTP::respond 302 Location "/irj/portal/"

 

}

 

}
