I am developing an application where every user has a subdomain
xyz will take him to his subdomain.
For the above alumclub.net, I am trying to set up the blog at blog.alumclub.net.
I have created another A record:
blog.alumclub.net A 192.168.0.100
But the above is not coming into effect because of the rule
*.alumclub.net -> 192.168.0.200
Because of rule 2, blog.domainname.com is not going to my blog hosted on posterous (http://alumclub.posterous.com/) instead it is going to my server and treating the blog as subdomain of user.
How can I solve this problem? Is it possible to solve?
