While the plugin expects the server to close the connection after
sending the response, the server initiates a HTTP/1.0-style persistent
connection.  The plugin doesn't handle this properly and awaits more
data until it runs into the timeout.

Could you check whether you can reproduce the problem using the current
snapshot and the "-H" option (in which case the plugin should request an
HTTP/1.1 connection)?  See:

Thanks, Holger
