This method enables the pluggable application upon service proxy system to reason the cause of network error. The pluggable application can take proper action against the errors by finding out about the error. If a network error occurs when proxy server is sending a request to Web server, the response time of this request becomes longer due to the error recovery by network layer i.e. TCP, UDP layer. If a large number of error retries for popular sites happens, it consumes available HTTP connection resource of this proxy server. Service proxy can avoid this catastrophic situation, if pluggable application can inspect the error in detail, and proper recovery actions are taken.
