Synopsis: The NoProxy directive in httpd.conf is not recognized State-Changed-From-To: open-closed State-Changed-By: marc State-Changed-When: Fri Aug 1 09:24:59 PDT 1997 State-Changed-Why: As listed in the documentation, NoProxy is only available in the 1.3 tree. It is in 1.3a1, but that release is alpha and not recommended for general use.
If you are fluent enough in C, you could take a look at http://www.apache.org/websrc/cvsweb.cgi and try to patch the changes in yourself. The files that are involved in that feature are mod_proxy.c, mod_proxy.h, proxy_ftp.c, proxy_http.c and proxy_util.c. This is, however, entirely unsupported.
