Cross Domain persistence

[Duncan Hall]

Hi,

I have a website that acts as the SSL ecommerce checkout for several 
other sites.  All of the sites are on the same public IP and live in a 
cluster of tomcat servers.

I need to maintain session persistence when moving from one domain to 
the SSL enabled domain and from http to https. Can anyone point me at a 
config example for this using Haproxy 1.5dev?

Thanks in advance,

Duncan
