Okay, let me re-phrase my question then:

Do you get the same intermittent problems if you tell the client java 
Application to connect to the site directly without using Squid?

No, I meant that there could genuinely be a temporary failure on the content 
server, which results in the HTTP/503 error.  Nothing Squid can do about that 
(especially since you're not using it in caching mode - what are you using it 
for?)
