Rsync over HTTP

[Amit Behere]

Hi all,

I have read all the documentation available on Rsync at the rsync webpage. I have also done a Google search for doing Rsync over HTTP. 
If you have to use Rsync over multiple networks you need to get past firewalls. Very few firewalls allow anything beyond HTTP port 80. Has anyone researched tunneling Rsync through HTTP and is there any documentation available.

Regards,
Amit
