create a sub domain

Question

hi...

If my website is hosted using IIS at http://www.domain.com

I want to make a subdomain for every user.
So, a user 'BillGates' signs up, and automatically my code creates
http://billgates.domain.com

thanks in advance...

create sub domain using HTTP Module show here code sample public class SubdomainModule : IHttpModule { public void Init( HttpApplication app) { // register for pipeline events app.BeginRequest += new EventHandler ( this .OnBeginRequest); } public void Dispose() {} public void OnBeginRequest( object o EventArgs args) { // get access to app and context HttpApplication app = ( HttpApplication )o; HttpContext ctx = app.Context; if (!(app.Context.Request.Url.Host.StartsWith( codebetter ) || app.Context.Request.Url.Host.StartsWith( www ))) { if (ctx.Request.Path.ToUpper() == /DEFAULT.ASPX ) { string [] domainParts = app.Context.Request.Url.Host.Split( . .ToCharArray()); if (domainParts.Length > 2) ctx.Server.Transfer( /explore/explore.aspx?q= + domainParts[0]); } } } } add the following to your web.config file: httpModules > add name =SubdomainModule type =Tompkins.Cs.Subdomains.SubdomainModule Tompkins.Cs.SubdomainHandler /> httpModules > for reference

You should create a wildcard subdomain and redirect all requests to another URL and parse out the page requested. In this case it would also redirect for employees who did not exist but it is probably a better option than attempting to maintain 5000 DNS entries with employee names. From MS: In the DNS Manager create a new Domain and name it *. Then open that new folder and add a Host record leaving the name blank. (It will give you a warning but it will work.)
