The RewriteCond effect will be negligible in comparison to the
resource usage involved in proxying. It is simply one regex, compared
to generating a whole new request to a different server. If you are
concerned about resource usage, the first thing to look at is if the
proxy is really necessary, and if it could be cached at the proxy
server.

It depends on what exactly you mean by "different handling". There is
no general answer to that question.

Yes, it's fine. You could probably alternatively use
ProxyPass /svn !
ProxyPass / http://othersite/
which avoids mod_rewrite.

Thanks, that makes sense. I'm running a Content Management System
(CMS) behind Apache and need Apache for SSL, ACL, and other TLAs

Yeah, I should have been a little less vague. Here's the
"different handling" part: 1) Apache to serve some pages for
a subversion interface and 2) Apache to proxy some requests
to the CMS server - both over the same SSL Virtual Host.
My guess is from what you're saying, that the RewriteCond is
probably a clean way to do this. At least it's not obfuscated.
