css capability question

We are an ASP providing a java application that has custom built in load balancing. We're starting to outgrow the model and I'm wondering if a CSS is a possible solution (I use one for a web application as well).

The problem is this: if a server goes down, all sessions try to reconnect and the JVM can't handle the onslaught of hundreds of simultaneous re-connects. If we employ a CSS, is there a way to limit the number of new connections within a certain time period?

Also, authentication takes place over one port, then the application connects over another port. Is there a way to have a client perform authentication and run the application on the same server?

Re: css capability question

you can't limit the number of connection per seconds. You can only limit the number of active connections with the command maxconnections.

Then to guarantee that the same server is used after login, you need some form of stickyness.

If you have a CSS layer 3 content rule which is not associated with a specific port, you can do sticky source ip to guarantee that the new connection on the different port will go to the same server.
