What application/gzip is
application/gzip is a gzip-compressed file (.gz). Don't confuse it with the Content-Encoding: gzip header, which compresses a response in transit — this type is for a file that *is* a gzip archive.
How it's used
You'll see this as a Content-Type value on requests and responses — for example Content-Type: application/gzip. It's the type associated with the .gz file extension. Application types cover structured data and binary formats — from JSON and XML to PDFs, archives, and Office documents.
