Timeout
A limit on how long a client or server will wait for a response before giving up. Connection timeouts occur when a TCP connection cannot be established. Read timeouts occur when data stops arriving. Gateway timeouts (HTTP 504) occur when an upstream server takes too long to respond. Proper timeout configuration prevents resources from being held indefinitely.
