I'm looking for a lightweight program in Common Lisp for communicating to
the web. Should take a URL and return the contents of the site. Should accept https sites. A code sample like (get-url "mywebsite.org") would be cool.

If it can push data via ftp and passwords etc. even better.

This usually has to be a wrapper around the (necessary complexity) functionality that the client has to expose

The usual suspects are edi weitz' drakma https://github.com/edicl/drakma
and `fukamachi's https://github.com/fukamachi/dexador - but these come
with the stack of dependencies and the subsequent dependence on
quicklisp.

A lightweight (light on dependencies) alternative was Jeff Massung's
suite of tools which included a http client
https://github.com/massung/http this was for CCL at the time I used it.
This worked well for me until he switched it over to SBCL-only, though I
had a stab at keeping CCL compatibility

I don't think it does FTP, but it surely does all those kinds of things in HTTP.

For FTP

CL-USER(4): (ql:system-apropos "ftp")
#<SYSTEM cl-ftp / cl-ftp-20150608-http / quicklisp 2021-10-21>
#<SYSTEM fftpack5 / f2cl-20200925-git / quicklisp 2021-10-21>
#<SYSTEM fftpack5-double / f2cl-20200925-git / quicklisp 2021-10-21>
#<SYSTEM ftp / cl-ftp-20150608-http / quicklisp 2021-10-21>
CL-USER(5):

Never tested, however FTP is a simple protocol, quite sure it does all
that.

Compared to HTTP/1.0, FTP is pretty complex. It negotiates and opens a separate connection see the PASV command.

most univ sites have stopped serving ftp. firefox dropped support for
ftp. citing maintanence is not a change for something so tested. there
is considerable capital-investment from above in killing off ftp.
