How does the ProxySG locate an object in its cache?

The ProxySG locates an object in its cache by performing a hash against the URL of the object. This approach is efficient because it allows for quick access to cached data without the need to search through the entire cache linearly. When a request for an object is made, the ProxySG calculates a hash value based on the URL, which serves as an index to quickly find the corresponding data in the cache.

Using the URL enables the ProxySG to uniquely identify resources as they are typically associated with specific web addresses. This method enhances performance as it reduces the time required to retrieve cached content, leading to faster response times for user requests. By efficiently managing how objects are stored and retrieved, the ProxySG optimizes the use of its cache and improves overall network traffic management.
