zsync 0.6 (Default branch)
zsync is a implementation of rsync over HTTP. It allows updating of files from a remote Web server without requiring a full download or a special remote server application. It uses a metafile, which is created on the server, to determine which parts of a file the user already has; it then downloads the remaining parts via HTTP. No special server or Web server module is needed. It also works with gzip files, and content on the server can be compressed to further reduce download times. License: Artistic License Changes:
Bugs were fixed, including a possible segmentation fault and problems making zsync files for large compressed downloads. Also, the mtime on downloaded files are now preserved. Image

phttpget

PHTTPGET(8)						    BSD System Manager's Manual 					       PHTTPGET(8)

NAME

     phttpget -- retrieve multiple files via pipelined HTTP

SYNOPSIS

     phttpget server file ...

DESCRIPTION

     The phttpget utility is a minimalist pipelined HTTP client, which is used to retrieve multiple files from one server, and saves the down-
     loaded files in the current working directory, using the last portion of their download path as file names.

     By making several "in flight" HTTP requests, it can dramatically increase performance when a large number of small files need to be down-
     loaded.

     The freebsd-update(8) and portnap(8) tools use phttpget to download binary patch files.

ENVIRONMENT

     HTTP_PROXY       URL of the proxy to use for HTTP requests.

     HTTP_PROXY_AUTH  Authorization parameters for the HTTP proxy.

     HTTP_USER_AGENT  The User-Agent string to use for HTTP requests.  The default is ``phttpget/0.1''.

     HTTP_TIMEOUT     Timeout for HTTP request in seconds.

SEE ALSO

     fetch(1), freebsd-update(8), portsnap(8)

AUTHORS

     The phttpget utility was written by Colin Percival <cperciva@FreeBSD.org> for use with portsnap(8) and later with freebsd-update(8).  This
     manual page was written by Xin LI <delphij@FreeBSD.org>.
