Last updated on SEPTEMBER 26, 2017

Applies to:

Oracle WebLogic Server - Version 10.3.1 to 12.2.1.3.0
Information in this document applies to any platform.

Symptoms

On WebLogic Web Server plugin 1.1 or higher version, it is observed that HTTP POST request does not fail over to available server instance. Meanwhile the error log shows message as below sample. 

Plug-in parameter IDEMPOTENT is ON by default. The expected behavior is, when it is set to ON and if the servers do not respond within WLIOTimeoutSecs, the plug-ins fail over the request to next available server. Why does not the plug-in fail over the HTTP POST request?
