[Note: I guess everywhere I said RewriteBase, I really meant per-dir
prefix.  The per-dir prefix is what is stripped at the beginning; the
RewriteBase is prepended at the end.]

I think you meant /var/www/.htaccess in that line.

Really?  I straced Apache 2.2.10 and it only starts processing .htaccess
files from the document root, so if the document root for domain2
were /var/www/sub , it would not read /var/www/.htaccess at all to
inherit any rules defined there.  Is your Apache behaving differently?
