Is there a way to avoid a proxy server closing Jboss HTTPS connection on long requests?

<div class="jive-rendered-content"><p>We have a client/server application running on Jboss 5.1.0.GA with JbossRemoting 2.5.3.SP1.</p><p>Clients make remote EJB3 calls to the server using https which is routed through a proxy server.</p><p>The jndi.properties includes this:</p><p><span style="font-family: courier new,courier;">java.naming.factory.initial=org.jboss.naming.HttpNamingContextFactory</span></p><p><span style="font-family: courier new,courier;">java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces</span></p><p><span style="font-family: courier new,courier;"><span>java.naming.provider.url=</span><a class="jive-link-external-small" href="https://SERVER:443/unified-invoker/SSLJNDIFactory/?dataType=invocation&return-exception=true" target="_blank">https://SERVER:443/unified-invoker/SSLJNDIFactory/?dataType=invocation&return-exception=true</a></span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>On some remote calls which run for several minutes, the proxy server terminates the HTTPS connection from the client.
