I originally took notes about this library in another document (preferring to keep all notes in this library). Read through that document again and create separate issues for anything that's not implemented yet.

If the user has library(archive) installed, add Accept-Encoding: gzip to the outgoing request header. If the response comes back with Content-Encoding: gzip then automatically decode it along these lines:

use_module(library(archive)),
archive_open(HttpBodyStream,Archive,[format(raw)]),
archive_next_header(Archive,_),
archive_open_entry(Archive,Stream).

Be sure to perform necessary archive cleanup.

I'm not sure if this is a good idea. The first argument of web:get/2 accepts a URL. In some sense, that argument represents the HTTP request. The second argument represents the HTTP response. What if we also accepted a list of options for the first argument:

• url - specifies the request URL
• auth(basic(User,Password)) - enables HTTP Basic authentication
• header(Name,Value) - adds an HTTP request header
• timeout - maximum time to wait for a response

Most of these are sugar for http_open/3 options so implementation should be fairly easy.
