Actually the way it goes is, the application code makes some HTTP calls through common libraries and Packetzoom framework, if linked in the app, can intercept these requests and reroute them to our proxy through packetzoom's own protocol. So we're not intercepting any particular wire protocol as such... the interception happens at a higher level. So your existing stack shouldn't matter.
