Hi there,

What is the better approach for load balancing on web servers? My services run in .NET and Mono, so they could be hosted on IIS or Apache2, and the will have to provide SSL connection.

I've read two main approaches, store the state in a common server and use sticky sessions, there is any other else?

I've read 3 diffent things about sticky sessions:

1)the load balancing device will know with which server did you start the connection and all the further connections from that host will be routed to the same server.

2)the load balancing devide read a cookie named: JSESSIONID

3)the load balancing devide read a cookie named: ASPSESSIONID

I'm a little bit confused, what will happen exactly? As the connections will be SSL there is not a chance for the load balancing devide of read the cookies, so then what?

About store the estate in a common server, what solutions do you know? I've read memcache is a good solution but is there any other else?

Cheers.
