Executing lua script on webserver

[Michael Gerbracht <smartmails@...>]

Hello,

I would like to generate a licence file using lua code involving some
information from a website. So if user goes to my website, makes some choices
and enters his personal data, this information should be passed to a lua
script (e.g. by writing/reading a database entry) which takes the provided
information and generates a licence file. This licence file should then be
send to the user (via e-mail or download).

My question is not about the lua script itself but I don't know whether it is
possible to run a lua script on a webserver. Can you give me some hint
whether this is possible and what it required to get it running? Also, is it
likely that my hoster (domainfactory.de) will allow me to run a lua script on
my website? 

thank you very much,
Michael
