http:// to https:// redirect not working

I believe you want to have requests to your VIP on x.y.z.77:80 redirected to a second VIP on x.y.z.77:443.

If that's the case, just use the original HTTP to HTTPS redirect rule on the x.y.z.77:80 VIP:

when HTTP_REQUEST {
   HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri]
   log local0. "client [IP::client_addr] redirected to: https://[getfield [HTTP::host] ":" 1][HTTP::uri]"
}

Then use the switch rule on the HTTPS VIP. Clients that access the VIP on port 80 should then be redirected to the same host and URI via HTTPS. Assuming the HTTPS requests are decrypted, the switch rule on the HTTPS VIP would route the request to the corresponding pool.

As your rule is looking for different domains on the .mil top level domain, I assume the client will get prompted to accept an invalid certificate. Nonetheless, they should still get redirected and passed to the corresponding node.

If you still see problems after verifying the rules are added to the correct VIPs, add log statements to each rule to see what is happening and check the /var/log/ltm log file for details.
