How many server workers are associated with each client worker when SGOS processes a client HTTP request?

The correct understanding is that the number of server workers associated with each client worker can be either zero or one, depending on whether the requested content is already cached or not. When a client HTTP request is processed by SGOS (Symantec Gateway Operating System), if the requested data is available in the cache, the client can be served directly from the cache without the need for a corresponding server worker. This is efficient as it reduces latency and load on backend servers.

However, if the requested data is not cached, the system will create a server worker to fetch the content from the backend server. Therefore, it is valid to say that there may be situations where no server worker is instantiated for a client worker, particularly when the request can be fulfilled using the cached response. Hence, this explains why the answer identifies the variability in the connection between client workers and server workers.
