switch http to https if header contains "SSL" =1

Looks like you have one missing } in the first irule and a misplaced } in the second one.

In the first one you have 5 "{" characters and only 4 "}" characters. You're not closing the "when" statement.

In the second one you have a second "}" immediately after the second if's test. This should really be at the end.

Here's what I came up with to fix it (there might still be problems, but this is what I found):

when HTTP_RESPONSE {
  if { [HTTP::header "SSL"] == 1 } {
    if { [TCP::local_port] == 80 } {
      HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri]
    }
  }
}
when HTTP_RESPONSE {
  if { [HTTP::header "SSL"] <> 1 } {
    if { [TCP::local_port] == 443 } {
      HTTPS::redirect http://[getfield [HTTP::host] ":" 1][HTTP::uri]
    }
  }
}
