/*

|
|
Two behaviours are considered acceptable, so there are two ways to
|
|
pass this test
|
|
|
|
a) Set data for the compressed resource:
|
|
* event.total reflects the Content-length of the gzipp'ed resource
|
|
* event.loaded how many gzipped bytes have arrived over the wire so far
|
|
* lengthComputable is true
|
|
|
|
or
|
|
|
|
b) If the implementation does not provide progress details for the compressed
|
|
resource, set
|
|
* lengthComputable to false
|
|
* event.total to 0
|
|
* event.loaded to the number of bytes available so far after gzip decoding
|
|
|
|
Implications of this are tested here as follows:
|
|
|
|
* If lengthComputable is true:
|
|
* Event.total must match Content-length header
|
|
* event.loaded should be a smaller number while resource is loading
|
|
and match Content-length when loading is finished
|
|
* Setting event.loaded to equal event.total for each progress event if the
|
|
resource is not fully downloaded would be cheating
|
|
|
|
* If lengthComputable is false:
|
|
* event.total should be 0
|
|
* event.loaded should be the length of the decompressed content, i.e.
|
|
bigger than Content-length header value when finished loading
|
|
