OT: Inserting Ads without breaking the SSL

["Saqib Ali" <docbook.xml () gmail com>]

This is a little bit off-topic. But I need to solve this mystery:

Recently a provider in Santa Clara, CA started to provide free Wifi
service. The only catch is that they insert Adds on the webpage see:
http://www.metrofi.com/advertisers.html (screenshot at the very bottom).

This does not require installation of any software. So seems to me
their proxy is somehow modifying the HTML webpage to add the Ads.

I would like to find out how this is done so that the intergrity of a
SSL enabled page is not lost.

Thanks
