Description

Title: Retry failed ext_authz requests

Description:

Is there a way to retry ext_authz requests after a network failure not an authorization service failure?

Contributor guide

Research direction
Study the ext authz filter implementation in Envoy, identify where network failures occur, and design a retry mechanism that distinguishes network failures from authorization denials. Consider adding a retry policy configuration to the filter.
