Subject RE: Possible to send 503 status over JK?
Date Tue, 25 Jul 2006 16:37:43 GMT
Hi Martin, doesn't the example you listed involve the webapp actually
running to return a 503 in a particular circumstance?  I'm trying to handle
a 503 when the webapp is actually stopped, by the manager app/JMX.  So
nothing code/config wise in the webapp would fix the problem that I can
think of, it would have to be a code/config change for tomcat itself.  This
is why I was looking for the default request handling pipeline order.

In my initial browsing of the code...
org.apache.ajp.RequstHandler::decodeRequest(Ajp13 ch, Ajp13Packet msg,
BaseRequest req) int
The comments for the return value say...
"@return 200 in case of a successful decoduing, 500 in case of error."
But I'm still reading

Again if anyone has any info that can point me in the right direction, I
would appreciate it.

-Rick

503 errors http://java.sun.com/developer/JDCTechTips/2001/tt0626.html
