Problem with a PACFILE VS

Rene, when you insert a proxy between the client and a server, you essentially create two network paths. You have the client side between the browser and the proxy, and another between the proxy and the server. What we need to assess here then is WHERE the traffic is failing. I'm assuming you performed the tcpdump on the client side, so you now need to run another capture on the server side of the proxy. If you don't see traffic to the server on the server side, then you can reasonably assume that there's something wrong at the proxy.
