Take the 2-minute tour ×  I have IIS running two sites + IIS
virtual folders (w3root) on a win 2k3 server. I wondered if
there were any way to also piggyback FTP traffic on that pipe by
using port 80 on the ftp server.  How would I do this and still
keep the web stuff running without interruption?  share|improve
this question  4 Answers 4  No, you cannot run HTTP and FTP on
the same TCP port of the same IP address. If you are looking for
a way to upload files via Port 80 to a web server, WebDAV may be
an option.  You may be interested in a tutorial on using WebDAV
with IIS on Server 2003  Don't forget about security! FTP is an
outdated and insecure protocol that should never be used over
the public internet, except for anonymous downloads. FTP sends
both your username/password and your data in plaintext. SFTP and
FTPS are reasonable alternatives.  If you cannot use SSL at all
times, enabling Digest Authentication will prevent your WebDAV
login passwords from being sent in plaintext.  share|improve
