In the mod_proxy + mod_perl servers scenario, CProxyPass was used to
redirect all requests to the mod_perl server, by matching the

A quick way to make dynamic pages look static:

Instead of keeping all your Perl scripts in I/perl and your static

+=head2 Upgrading mod_perl Heavy Application Instances
+
+When using a light/heavy separation method one of the challenges of
+running a production environment is being able to upgrade to newer
+versions of mod_perl or your own application. The following method can
+be used without having to do a server restart.
+
+Add the following rewrite rule to your httpd.conf file:
+
+ RewriteEngine On
+ RewriteMap maps txt:/etc/httpd.maps
+ RewriteRule ^(.*) http://${maps:appserver}$1 [proxy]
+
+Create the file /etc/httpd.maps and add the following entry:
+
+ appserver foo.com:
+
+Mod_rewrite rereads (or checks the mtime of) the file on every request
+so the change takes effect immediately. To seamlessly upgrade your
+application server to a new version, install a new version on a
+different port. After checking for a quality installation, edit
+/etc/httpd.maps to point to the new server. After the file is written
+the next request the server processes will be redirected to the new
+installation.
+
+=head2 Blocking IP Addresses
+
+The following rewrite code blocks IP addresses:
+
+ RewriteCond /web/site/var/blocked/REMOTE_ADDR-%{REMOTE_ADDR} -f
+ RewriteRule .* http://YOUR-HOST-BLOCKED-FOR-EXCESSIVE-CONSUMPTION
[redirect,last]
+
+To block IP address 10.1.2.3, simply touch
+
+ /web/site/var/blocked/REMOTE_ADDR-10.1.2.3
+
+This has an advantage over Apache parsing a long file of addresses in
+that the OS is better at a file lookup.
