Upload progress example
This example illustrates how to create an upload form with a progress bar. It uses JQuery for simplicity of implementation.
It has a filesize limit of 32 megabytes. If this limit is exceeded, a 413 error code response is returned.
Download progress example
This example shows how it is possible to create a progress bar for downloads aswell. It's not too useful in real world, but I'm sure people will come up with worthy usecases.
The link goes to a 1 megabyte file and is throttled to 32 kilobyte/s for illustration purposes.
