Problems with Arrowpoint cookies for clients behind a Proxy

Question

I have in a WebSite clients being load balanced using Arrowpoint cookies to a virtual Server. The CSS load balance between three Apache real servers.
I have some clients that are behind some kind of Proxy Cache and I have seen with a sniffer that the proxies causing the problem Re-use proxy to our server connections for different requests for multiple clients.
Then, as I understand the CSS make the forwarding decission based on the cookie of the first request for the first client behind the proxy after establishing the HTTP connection, but when there is a request from other client using this same connection (that must be forwarded to other real server) the request is forwarded to the original web server and fails because we need sticky connections.
I thought that this wasn't correct but I have read some documents that say that this is called a Proxy role as a "connection cache". Then my question is if there is any workaround for this problem.
Thanks

Answer 1

I believe your problem is that the proxy open a few persistent connections with the CSS and loadbalance your client's request over them.
Once the CSS has associated a connection with a service, it does not look into the request anymore.
The solution is to disable persistence on the CSS with the command 'no persistent' and 'persistence reset'.
