[Qt-interest] What does data: scheme do in network access

[Tony Rietwyk]

Hi Thiago, 

I'm curious.  You refered to scheme "data:" in your response to Patric's question about QNetworkAccessManager.  

What does this protocol do and when is it appropriate to use it? 

QNetworkAccessDataBackend doesn't have any documentation. 

Is it a way of querying if an item is already in the caches? 

Or maybe it just returna the payload after the request headers? 

Thanks, 

Tony.
