Need help - Before i pull my hair out!!!

Sorry... the format for string map is:

set my_new_string [string map {$find1 $replace1 $find2 $replace2} $original_string]

You can specify just one pair of find/replace strings if you want.

If you wanted to minimize the steps, you could use something like this:

when HTTP_RESPONSE {
   if { [HTTP::status] starts_with "3" and [HTTP::header "Location"] != "" and [HTTP::header "AP_NO_SSL_REDIR"] == ""} {
      HTTP::header "Location" [string map { [concat "http://"[HTTP::header "AP_LOCHOST"]] [concat "https://"[HTTP::header "AP_LOCHOST"] } HTTP::header "Location" ]
   }
}

Note that I didn't actually test this, but I think it matches the gist of what you're trying to do.

If you run into problems, try updating the longer version and check the logging in /var/log/ltm to see where it's failing.
