Conditional RewriteBase

Here's one for you all...

I have a situation where I need to define the RewriteBase based on what
the %{HTTP_HOST} value is.

For instance, if I have a request for http://www.example.com I don't
need to even set the RewriteBase. However, if I get a request for
http://ssl.exmaple.com I need to set the RewriteBase to /ssl_dir

Unfortunately, I have no control over the server at all, and am limited
to using the .htaccess file. Basically, they are two different machines
with the same set of files set as DOCUMENT_ROOT (most likely one is an
NFS mount or something).
