I think the suggested subdomain solution would be a lot more what you want. {client}.{my-company}.com is a lot more goodlookin' as a domain than www.{my-company}.com/clientname 🙂

there is common functionality we are building in a single SS site for different clients, and we want to expose the functionality on different domains/sub domains

I would suggest subdomains over folder mapping, as it's a lot easier 🙂

will check that out. Subdomains was also a possible solution to this

Because if so... why not use subdomains that point to the subfolder?

Hmmm, what are you actually trying to accomplish? Have multiple sites in the same docroot?

...so worst case would be http://www.mydomaininghere.com would redirect to http://www.mydomaininghere.com/subfolder/

we're actually hoping just to go one level deep in the site tree...
