Explicit proxy bypass non-standard HTTP ports

[Kelly C]

Is there an easy method to configure the Ironport to only inspect 80/443 and bypass any other ports with a explicit proxy deployment? I know this can be done in the browser on an IP basis but we would like to set this up on the Ironport WSA instead?

You should be able to do this with a proxy.pac file.

Wikipedia has a basic guide.

I imagine you could use shellExpMatch and make sure no port is specified, and that would do the trick.

ps. You host the proxy.pac on the Ironport, and your clients download it from there and auto-configure themselves.

You can deploy WSA in transparent mode by configuring WCCP.
