In the Cluster type = 1, due to the consistent hashing used in the content storing, the URL store is load balanced to all the cluster members. in production, you may need to add high available service such as GSLB and LVS etc, or do the balance/failover your own way, choose on you own needs. back in the inktomi age, the WCCP can work with Cluster to provide a more efficient management in local caching deployment, but it may not work that well now. - Yongming Zhao 赵永明 在 2015年7月29日，上午8:42，hzwulibin <[email protected]> 写道： Hi, In my case, i want to use trafficserver as a cache proxy; so my application is configured to get data from the server A if no cluster situation. But i'm wondering if it will still works well in the cluster. You memtioned load-bancing, so does it need a load bance between my application and trafficserver cluster? Or should i deal with it in my application? Yeah, maybe both are fine, anyway, i want my model be as simple as possible. Any suggestions about this?
