FreeBSD Postsnap via https

Hello,

I was wondering if there are any https servers available for freebsd
portsnap ? I would like to use portsnap behind my companies proxy servers.

But alas they will not allow large compressed files through the proxy, which have alot of small files contained within the file. Obviously they download the file and then decompress it to scan it for virus/malware/bad stuff etc.

Except for obviously for ssl connections they are passed straight through.

Are there any portsnap servers that are accessible by https ?
I do a similar thing for gentoo when using portage.

edit /etc/portsnap.conf
add or change SERVERNAME=portsnap.hshh.org
