Java Applet Proxy Problem

[andyv12]

Hi,

I have been running Wingate Pro 5.2.3 for a long while now without issue as my Proxy Server (and Mail Server) on a dual-homed Dell Poweredge server running Windows 2000 Server.

A very important client wants us to connect to a webserver on the internet that is running an application which causes a Java applet to execute inside of either Internet Explorer 6.0 (Windows) or Safari 1.3 (Mac).

The connections are running excruciatingly slow on either platform, although they ARE eventually being made.

I have attached the Java Console log pulled from a Windows XP machine running Java 1.5 within IE 6 as we connected to their site and application.

The application developer says that they only support CERN proxy servers and they claim that Wingate is a SOCKS proxy server and is not CERN proxy compatible.

Hence, they want me to re-engineer my network security solution to allow their application to run properly.

When I connect to their application from my home where I'm not running a proxy server, the application runs flawlessly.

Can you help shed some light on the situation for me? And confirm if CERN compatibility is the issue?

And why do they think Wingate is a SOCKS proxy server? I describe Wingate is a robust Application-level Proxy Server that supports a wide variety of protocols, of which SOCKS is only one.

Thank You.

Also submitted support ticket. Current Status:

When this particular Java app connects to port 443, there is 4 min delay via 5.2.3 and 40 second delay via 6.2.0. Have done packet captures and waiting for dev to assess after weekend.

Suggested work around:
Remove "Secure" Proxy value from Internet Explorer --> Tools menu --> Internet Options --> Connections tab --> LAN Settings --> Advanced
And then will allow alternative connection method to invoke (NAT). Need to create policy in ENS allowing access to server port 443 for the LAN Clients because not allowed full NAT.

Filter 1
This criterion is met if Server Port equals 443

CERN Proxy very old name, now called HTTP Proxy; i.e. WinGate's WWW Proxy Service.
