Web Server HTTP Header Internal IP Disclosure

if the problem is the Location header that expose an IP address you can try with a simple irule that will rewrite the Location, for example:

when HTTP_RESPONSE {

  if { [HTTP::header is_redirect]} {

    HTTP::header replace Location [string map -nocase {1.1.1.1 www.something.com} [HTTP::header value Location]]

  }

}

But you can implement something similar using an LTM policy.
