Add auto-detection of the collector URI protocol

[fram03]

With Emitter constructor we can choose HTTP method to use, but what about forcing https? Js library offers "forceSecureTracker" configuration field. Is there something for as3 library?

Nice idea! Added to milestone

@alexanderdean This is already possible. It is however undocumented in the wiki, Emitter signature is
Emitter(uri:String, httpMethod:String = URLRequestMethod.GET, protocol:String = "http")

We can chose to provide a forceSecureTracker on the Emitter and make it public or expose it through the tracker.

Thanks for diving into this @nakulgan -

• Does protocol:String force the protocol used to connect?
• Is there no concept of auto-detection?

A simple interpretation of that argument would suggest that there is only currently forcing, and there is no auto-detection of host page protocol available currently - but no idea if that's actually true...

[nakulgan]

That is correct, protocol auto-detection is not supported. It makes more sense to add auto-detection feature along with forcing.

Thanks @nakulgan - my recommendation is that we:

• Switch the protocol:String from a string to an enum of HTTP, HTTPS, AUTO, with AUTO the default option
• Rename this ticket to reflect this
• Don't add forceSecureTracker and forceInsecureTracker methods because they add extra API surface area / usage complexity (you have to remember to call an additional method)

This diverges the AS Tracker from the JS Tracker, but it's closer to the mobile trackers and it's simpler to explain to people.

Thoughts @yalisassoon @jbeemster ?

All sounds good to me!

[nakulgan]

Sounds good. Thanks @alexanderdean @jbeemster
