REDIRECT IRULE need some help

this is an example for http. for https, just change HTTP::redirect command from http to https.

e.g.

 config

[root@ve11a:Active:In Sync] config  tmsh list ltm rule qux
ltm rule qux {
    when HTTP_REQUEST {
  if { [HTTP::host] ends_with ".com" } {
    HTTP::redirect "http://[string map {.com .org} [HTTP::host]][HTTP::uri]"
  }
}
}

 test

[root@ve11a:Active:In Sync] config  curl -I http://172.28.24.10/something -H "Host: mobilebank.com"
HTTP/1.0 302 Found
Location: http://mobilebank.org/something
Server: BigIP
Connection: Keep-Alive
Content-Length: 0

[root@ve11a:Active:In Sync] config  curl -I http://172.28.24.10/something -H "Host: www.mobilebank.com"
HTTP/1.0 302 Found
Location: http://www.mobilebank.org/something
Server: BigIP
Connection: Keep-Alive
Content-Length: 0

This should work for you:

when HTTP_REQUEST {
 if { [string tolower [HTTP::host]] ends_with "mobilebank.com" } {
  HTTP::redirect "https://www.mobilebank.org"
  }
}

Keep in mind though that if an HTTPS request arrives for mobilebank.com, you'll need to terminate the SSL in order for these iRules to do any redirection.
