itk plus mode is an additional mode to deploy itk based hostings
which should be a bit more performant. The idea is that we have
two apache-instances running:
A) prefork based, listening on the external interface
B) itk based, listening on the loopback interface
A) will serve all static webpages, as well as possibly serve all static
content of dynamic websites. All requests to dynamic content will be
redirected to B). The idea is that A) doesn't load any modules to server
dynamic content at all.
B) will serve all the dynamic scripts of a vhost.
This will mean that for vhosts (static ones) as well as static content (all
none dynamic scripts) we can benefit from the fast prefork model, while we
can use itk's security model for all the dynamic scripts.
There are two new additional run_modes:
- proxy-itk: this just passes all requests to apache instance B). This one
is similar to plain itk based mode and should be used for vhosts
that shouldn't (yet) changed to the mixed mode.
- static-itk: this passes only requests to dynamic scripts to B) while all
static content is served by A). Beware that the user with which
A) is running should be member of the run group of B) and all
static files need to readable by the group. This reduces
the security model you have with plain itk, as the prefork
apache user will be able to read php (config-) files of any
vhost that runs in static-itk mode. If you want to keep
the level of security for a certain vhost, you need to run
the specific vhost in proxy-itk mode.
Note 1: you cannot run vhosts in itk mode and others in proxy or static
itk mode. There is a duplicate file resource definition that
blocks that possibility.
Note 2: This mode works currently only on CentOS based systems, as no
work have been done so far to implement an init.d script that's
able to run 2 apache instances.

We are now able to select how apache should log accesses. These
modes are:
* default: as you would use it
* semianonym: no ips are logged for CustomLog, ErrorLog still logs
ips
* anonym: no ips are logged for CustomLog, ErrorLog is sent to
/dev/null
* nologs: all logs are sent to /dev/null

suspicious requests, set to 'false' to log all requests (as before)
