use the `--with-ssl' configure flag. You need to have OpenSSL

installed.
|
||||
|
||||
** "Keep-alive" (persistent) HTTP connections are now supported. This
|
||||
means that multiple requests from the same hosts are now much faster.
|
||||
** Cookies are now supported. Wget will accept cookies sent by the
|
||||
server and return them in later requests. Additionally, it can load
|
||||
and save cookies to disk, in the same format that Netscape uses.
|
||||
|
||||
** "Keep-alive" (persistent) HTTP connections are now supported.
|
||||
Using keep-alive allows Wget to share one TCP/IP connection for
|
||||
many retrievals, making multiple-file downloads faster and less
|
||||
stressing for the server and the network.
|
||||
|
||||
** Wget now recognizes FTP directory listings generated by NT and VMS
|
||||
servers.
