Configure this client to retry or not when a connectivity problem is encountered. By default, this client silently recovers from the following problems:
Unreachable IP addresses. If the URL’s host has multiple IP addresses, failure to reach any individual IP address doesn’t fail the overall request. This can increase availability of multi-homed services.
Stale pooled connections. The ConnectionPool reuses sockets to decrease request latency, but these connections will occasionally time out.
Unreachable proxy servers. A ProxySelector can be used to attempt multiple proxy servers in sequence, eventually falling back to a direct connection.
Set this to false to avoid retrying requests when doing so is destructive. In this case the calling application should do its own recovery of connectivity failures.
