Redirect Folders

I use MultiSite WordPress with Domain Mapping.

I have mapped one of the Blogs (http://allblogs.com/subfolder/) to http://specialblog.com.

Now i have the Problem that the mapped Blog didn’t find the CSS-Styles.
I want now to Redirect all from http://specialblog.com/wp-config/ to http://allblogs.com/subfolder/wp-config/

How can i do that?
