I would like to be able to redirect some http request through proxy usign wildcards, while others go straight through to the net. (See patterns here for detailed info.) The foxyproxy plugin for firefox can do this, but can I use it somehow in Diablo, or is there some other alternative?

I am not sure it can do exactly what you ask, but there is privoxy

Thanks for the reply. I'll try that! Actually I'm already running it on my home box, and thought of trying to configure it for the task, but it's even better if it's running on the tablet!
