http fallback host on a https Virtual Server

Hi All,

 

I am trying to build or find a Irule that will display a sorry page when the pool is down on a 443 URL. I found the following but it looks like it is missing a key portion on how to identify if the pool is up or down. For this URL, the 443 is a pass through as the servers are doing cert termination. I do have a ssl cert and profile per the Irule but I am not sure how the maintencace_redirect flag is getting set.

 

 

when CLIENT_ACCEPTED

 

{ Set this flag to 1 to decrypt the SSL and send a redirect to the client. Set to 0 to pass the SSL through without decrypting it. set maintenance_redirect 1

 

 

0 log local0. "[IP::client_addr]:[TCP::client_port]: Received connection with maintenance flag set to $maintenance_redirect"

 

 

Check if the maintenance flag is disabled (set to 0)

 

if {$maintenance_redirect==0}{

 

 

Disable the client SSL profile so the HTTPS traffic is passed through encrypted to the node

 

SSL::disable

 

 

Disable the HTTP profile as we're not going to redirect this request HTTP::disable log local0. "[IP::client_addr]:[TCP::client_port]: Maintenance flag is disabled"

 

}

 

}

 

 

when HTTP_REQUEST {

 

The HTTP_REQUEST event is only triggered if the maintenance flag is enabled and the client SSL and HTTP profiles are left enabled

 

 

Redirect the client HTTP::redirect http://redirect.target.com/SorryPage.html

 

 

log local0. "[IP::client_addr]:[TCP::client_port]: Redirecting request"

 

 

 

}
