# `--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.
