Squid acts as a HTTP->FTP gateway on requests for ftp:// URLS.

The currently supported HTTP methods on ftp:// URLs are:
  GET
  PUT
  HEAD

which gets translated to suitable FTP commands by Squid as per the
guidelines outlined for ftp:// URLs in RFC1738 section 3.2.

GET is used both for file retreival and directory listings.

Binary and Ascii file retreival is supported. If no explicit format is
requested Squid guesses using it's mime.conf table which tells Squid
both the ftp transfer mode to use and content-type to assign to the
reply. Explicit requests for ascii or binary uses text/plain or
application/octet-stream respectively for the content-type.

Directory listings uses LIST or NLST depending on the format type
specifier in the URL. Requests without an explicit format uses LIST,
while explicit requests for directory format uses NLST.

PUT in addition to storing files using STOR it also automatically
creates directories with MKD if needed. Or only creates directories if
the URL ends in / and the content-length is 0. If the URL ends in / and
content-length > 0 then STOU is used instead of STOR allowing the FTP
server to assign a suitable file name to the uploaded content.

GET uses REST is the request is a range for the remainder of the file.

Support could be added for more HTTP methods such as DELETE mapped to
DELE/RMD but nobody has shown any interest in this.
