It doesn't have to rely on a stateful HTTP connection. You already  
most likely use some server-stored state based on cookies/whatever. So  
among that server state you could also keep the opened IMAP  
connection. I guess the main issue here is that it doesn't work all  
that nicely if the HTTP requests get redirected to different servers  
randomly.
