what is the web server type of Serv-U (i.e IIS, Apache,..), what is the language that it uses for web server (i.e asp.net, asp, JSP,...), if using a database what is it ?
You can verify this by checking the returned headers on the demo server: SolarWinds Serv-U File Server
"Server:Serv-U/15.1.2.215"
Serv-u uses it's own webserver.
A DB is optional. It can use many different types of DB http://www.serv-u.com/serv-u_db_integration_guide.pdf
Many Thanks.
