- All Implemented Interfaces:
ExecChainHandler
@Contract(threading=STATELESS) @Internal public class HttpRequestRetryExec extends java.lang.Object implements ExecChainHandler
Request executor in the request execution chain that is responsible for making a decision whether a request that failed due to an I/O exception or received a specific response from the target server should be re-executed.Further responsibilities such as communication with the opposite endpoint is delegated to the next executor in the request execution chain.
If this handler is active, pay particular attention to the placement of other handlers within the handler chain relative to the retry handler. Use
ChainElement.RETRY
as name when referring to this handler.If a custom handler is placed before the retry handler, the handler will see the initial request and the final outcome after the last retry. Elapsed time will account for any delays imposed by the retry handler.
A custom handler which is placed after the retry handler will be invoked for each individual retry. Elapsed time will measure each individual http request, without the delay imposed by the retry handler.
