Fiddler & Proxy

I’m trying to use Fiddler with Ignition to monitor some traffic I’ve got going back and forth with a web service, (communications happen from a Gateway module I’ve developed). I’ve read that I can use the following …-Dhttp.proxyHost=localhost -Dhttp.proxyPort=8888… as VM arguments. Can I utilize these somewhere within ignition.conf safely or is their another, preferred approach to what I’m trying to accomplish?


I imagine you can use these safely under the “Java Additional Parameters” of ignition.conf. Obviously these settings are JVM-wide, so if another module comes along and starts looking at those one day you may have a problem, but I don’t think Ignition ever looks at either of those properties.

That being said… I can’t exactly say for sure everything is going to work :wink:

Edit: Looked closer; you’re telling Java to use a http proxy. Interesting. I can only think of a handful of outgoing HTTP requests the gateway makes, and I guess there should be no problem with them going through a proxy?

Thanks Kevin, I’ll be giving it a go later this afternoon, will reply with how it goes. I figured I’d throw this post up now to potentially save me some digging/troubleshooting later.
