I am slightly confused. The 501 error is coming from the Glassfish server so I would post into that alias. However I did notice 1 thing. The POST body contents
The content-length is given as 46 but that is 47 chars, That might be caused by the encoding of the "/" as %2F. it looks like "=pass" is being sent as the method.
I would do a separate snoop on the conversation on what is incoming to the Web server as the one above looks confused. We see a POST, which is given a 302 then
a GET. Can you split out both sides so we can see what comes in. Also check for unprinted chars.
Is there anyone can solve this issue?
Because i found the same problem when using iPlanet Web Server.
This error randomly accour when access the web url.
HTTP 501 is not accour when i directly access each instance url without using LB( iplanet web server).
