When requested with Firefox, 32 and 0 are missing. Why?
回答1:
The chunked transfer encoding is a sequence of chunks where each chunk consists of at least a size indicator and the chunk data.
In this case 32 and 0 are the size indicators in hexadecimal notation that denote the length of the following chunk data. A chunk size of 0 denotes the end of the chunked data stream.
