Making a third-party hosted blog look like a folder on the main domain

[jtroia]

I have a client that has a "completely pristine" Microsoft.net web environment that is unwilling to put a wordpress installation on their server.

Their management team wants a wordpress blog for the marketing department.  Is there a means where we can host the wordpress blog with a regular hosting company but yet have it appear as part of the main site e.g., mainsite.com/blog vs. having to put it in a subdomain (blog.mainsite.com) and lose all the SEO benefits of the blog content?

I am not very familiar with IIS, but i think this link should help you do this:

I believe IIS servers have an Application Request Routing plugin which can handle this need. Please refer to the following article: http://www.seomoz.org/blog/what-is-a-reverse-proxy-and-how-can-it-help-my-seo
