--compressed

Request a compressed response using one of the algorithms curl supports, and automatically decompress the content.

Response headers are not modified when saved, so if they are "interpreted" separately again at a later point they might appear to be saying that the content is (still) compressed; while in fact it has already been decompressed.

If this option is used and the server sends an unsupported encoding, curl reports an error. This is a request, not an order; the server may or may not deliver data compressed.

WARNING: when decompressing data, even tiny transfers might be expanded and generate a huge amount of bytes.
