Author IHS Http plugin fails on esiParseDate: unrecognized date format

2005-10-24, 5:07 pm


After doing a requestdispatcher.forward in WAS 5.1 the Http server plugin seems to fail passing de request data through to the IHS server resulting in a blank screen in my browser. The warning in the http plugin trace:

WARNING: ESI: esiParseDate: unrecognized date format: 'Thu Oct 20 18:50:57 CEST 2005'

Weird thing is: other applications do work, and I checked all configuration options I could find.

What could cause this, or how I can influence the date format in ESI?

regards, Bastiaan.



I'm running Was51 on Windows server 2003, IHS-2.0.47.1.

The log on de HTTP plugin trace:
