Load-balancing cache arrays in V9

The cache rule that the original poster was looking to replicate had additional functionality surrounding hot pools and cool pools. The functionality in 4.x made it so that an array of caches wouldn't all get the same content in each cache (thereby using up all of the drive space on all of the caches with the same data).

 

 

However, it would allow content to be spread across all cache servers if the content was frequently requested within a certain period of time (making the content "Hot").

 

 

Additionally, an iRule is needed in version 9 so that in reverse proxy cache scenarios, request from the internet to a particular vip would be directed to the cache servers in a particular pool while requests from those same cache servers to the origin servers would be directed to the origin servers in that pool.

 

 

This is useful for the "vip bounceback" scenarios where users had one vip for their particular site with one pool that contained by the cache servers and the origin servers. This allows for easier cookie persistence and priority load balancing with great failover scenarios within the pool.

 

 

It would be nice to have both of these rules made and templates for download with the iRules editor.
