Let’s suppose your app makes a lot of http requests at once, and you need a good administration for that. Based on used browser your app is running on, you are only allowed to limited request count – mostly its 2 requests per domain, the remaining ones are sitting in browser buffer waiting to finish those actual. URLRequestBuffer is handy class that lets you manage URLRequest-s. E.g. you are creating image gallery and request hundreds of images in gallery at a time, now when user navigates throug the images you need to make some request more prioritized before others, some to be canceled, some may timeout etc. Here comes URLRequestBuffer in scene.
