I found this (2 years after the post, but maybe it will help others)
I'm using SOAP::Lite 0.71, and it works
setting this variable:
$SOAP::Constants::PATCH_HTTP_KEEPALIVE=0;
Its almost documented in SOAP::Constants
So the code should be something like:
$SOAP::Constants::PATCH_HTTP_KEEPALIVE=0;
my $soap= SOAP::Lite
-> readable(1) # Opcion de debug para ver mas lindo el XML
-> ns('Hello')
-> proxy($PROXY, keep_alive => 1, timeout => 30 );
print $soap
-> sayHello($name)
-> result . "\n\n";
