I am planning to run a small ISP which I'd like to put all users behind a proxy server and a NAT box (so they won't need configuration and it will be forced).

So, I have here two connections to internet which I want to bond them in my proxy server so it will download the whole page on multisession links for all images and elements in each webpage.

for example, http://www.linuxforums.org/index.htm contain 20 jpg file and 2 gif file and probaby one swf file, I want my proxy to request for each file in different session using both Available link and transfer it to user immediately.

is that possible? how?

Thanks in advance
