Help with HTTPS_Rewrite iRule

I'm not certain I've understood the question correctly.

When I need to redirect all sites to HTTPS except a select few domains, I do like Vijay: create an irule

when HTTP_REQUEST {
    set vhost  [string tolower [HTTP::host]]
 
    switch $vhost {
        "http-domain1.local" -
        "http-domain2.local" { 
              #now it uses the default settings of the vs, including any default pool you might have selected
         }
         default { 
              #Send a redirect to https - 307 to tell the client that it needs to use the same method as when it send the request to this port
              HTTP::respond 307 Location "https://[getfield [HTTP::host] ":" 1][HTTP::uri]" 
         }
    }
}

If you have a lot of sites that need the exception you might be better served with a data group. It will make the irule shorter, however, every time you troubleshoot you'll have to look an additional place.
