[squid-users] Can SQUID change the destination address from ip to hostname?

[Foxy Lady]

I try again asking the ML if

- can Squid change the destination address of a call?

I mean, something like

<url_rewrite_command> $destination $Host

original $destination is 104.26.9.59:443
$Host is the original HTTP Header "Host: xxxxx" alias "api.myip.com:443"

So, a call to
https://104.26.9.59:443/test
will become
https://api.myip.com:443/test

Thanks.

SOCKS5 works with 1st level tcp, so send ip addresses, i need some tool, or Squid workaround, which can force a reverse dns. I know, it's quite impossible if a ptr record is not found in dnses, but... i try..
