FlushBuffer does not commit the response when servlet/command caching is enabled on the application server and ESI caching is enabled on IHS.

Troubleshooting


Problem

The J2EE flushBuffer API specification is not adhered to when servlet/command caching and esi caching are enabled. Invoking flushBuffer does not commit the response.

Symptom

An application may continue to add headers or set content length that normally would be rejected because the response is committed when flushBuffer is invoked.
