Can I set up Orchard CMS to be a sub directory of my "real" web site?

I have a web site and I would like to add some CMS capabilities to it (blog, forum, comments, rss, etc...).
Ideally, I'd like to co-host my existing asp.net MVC web site with a CMS like Orchard which should be under mysite.com/cms or mysite.com/blog.

How could I set that up ?


Alternatively I suppose one could set up a sub domain such as cms.mysite.com but I'm wary of deployment complications and SEO implications. Any feedback on such scenarios ?

I suppose I could also do the other way around and have my real web site a sub directory, and have the CMS be at the root of the site. I just need to marry the two together.
I'd like to avoid URL rewriting if possible as suggested at

as it can have its own complications (e.g. the application is not aware of its real url).

Thanks

Orchard is not designed to add capabilities to an existing site. It needs to run in its own IIS application.
