Is there a way to create userdomain.mydomain.com through asp? I would like to be able to create sub domains for the people that enroll on my site. My site has its own ip address and has its own domain but it is going to be done through a web hosting company. If it were possible for me to do it AND they allow unlimited sub domains would it be possible to do it through asp or would it be a security issue? Anybody done something like this before?
