I will if I find them back... cvs updating didn't show me differences 
which surprises me a bit...

Thanks... can quote the someone if you wish... sourceforge user polx in 
case.

Right... but when you use web-services from a far-away client browser, 
it's considerably higher... add to it a few proxies underway...
Is it harder on the client or on the server ?
On the server we shall be using Tomcat anyways which does make his own 
management of keep-alive, I believe (am I wrong?). It should, thus, 
"just" be done for the client where, I though, Http-Client should be 
somewhat friendly.

Note also that XML-RPC is particularly keep-alive savvy since it 
requires the content-length both at request and response... this is a 
fact that has annoyed a large amount of people but allows very nice 
connection management...
