Which caching technique emphasizes the cost associated with server bandwidth in the ProxySG?

Cost-based deletion is a caching technique that focuses on the financial implications of server bandwidth usage in the ProxySG environment. This method prioritizes the deletion of cached objects that incur high bandwidth costs when fetched from the origin server.

In a scenario where bandwidth consumption directly correlates to operational expenses, implementing cost-based deletion allows the proxy to maximize efficiency by retaining the most economical objects while removing those that unnecessarily strain the bandwidth. This approach helps in managing resources more effectively, ensuring that frequently requested content with lower bandwidth costs is preserved in the cache, while expensive items can be purged when resources are limited.

This technique is particularly advantageous in environments where bandwidth costs can fluctuate significantly or where high-volume traffic necessitates a careful balance of stored content to minimize operational expenditure.
