Yes. Turn on automatic directory indexes on the server. For uploading some extra work is required, but it is possible - the server should handle PUT request and store the file. -- Alexander.

Re: [lftp] FTP-over-HTTP
HI folks, thanks for the answer. I was reading mod_proxy_ftp documentation from apache and it states that it cannot upload files using ftp commands, only http post. http://httpd.apache.org/docs/current/mod/mod_proxy_ftp.html#ftpnonget Since not only I need to upload files, but also have pause-resume functionalities, I was wondering if apache was the right choice for the server side. Does it make sense? Which web server would be the most appropriated for communicating with lftp? On Thu, Mar 19, 2015 at 4:22 AM, Alexander V.
