           Summary: Add SetEnvIfIP to set env vars depneding on ip subnet
                    matches
           Product: Apache httpd-2
           Version: 2.3-HEAD
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: PatchAvailable
          Severity: enhancement
          Priority: P2
         Component: mod_setenvif
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: rainer.jung@kippdata.de


mod_authz_host allows Allow/Deny to depend on the presence of an environment
variable. Although it would be nice to set appropriate env vars once and then
use the env var in various places inside Allow/Deny, this doesn't really work in
practise, because there is no clean way of setting them w.r.t. IP addresses.

In simple network cases, people use string patterns and setenvif. When more
complex netmasks are involved, string matches against IP addresses don't work well.

The attached patch includes SetEnvIfIP that allows all notations, that
Allow/Deny provide (ful IP, partial IP, network/netmask, network/nnn CIDR).

I provide a patch against trunk (r420983, which is actual today) and one against
2.2 (r421103).

IP matches are allowed against remote_addr and also server_addr (because the
latter was simple, but maybe not really useful), also there are domain name
matches, which are allowed against everything that mod_setenvf accepts.

If there is some interest, I would see, how to also provide this feature as a
RewriteCond fpr mod_rewrite.

The new SetEnvIfExpr directive allows to match by subnet/netmask.
See r1039900
