Hello, I have two domains called 1 and 2. In domain 1 I am using iframe to load content from domain 2. Inside iframe for each and every request sessionId is changing every request. Any idea to maintain session constant in side I frame? Thanks

The web server / app server won't care that it's being called from an iFrame or another page all together. Does "domain 2" have an application.cfc / application.cfm? Is session management turned on? Or are the two domains pointing to the same server and application? The other thing to look at is the cookie management. Some browsers are blocking sub-domain cookies by default now that could cause some weirdness -- but usually in that case, there just wouldn't be any ability to transfer data between page calls.
