Will the rewrite module respect the order of the rules in the config file and execute the rules in order?

The manual says:

Rewrite rules are applied to the results of previous rewrite rules, in the order in which they are defined in the config file. The URL-path or file-system path (see "What is matched?", above) is completely replaced by the Substitution and the rewriting process continues until all rules have been applied, or it is explicitly terminated by an L flag, or other flag which implies immediate termination, such as END or F.

In my apache configuration, I am using a scripting language (tcl through apache rivet) which implements a "heavy" application, something that takes some minutes to start when apache starts a new process.

Is there a way to "separate" these "heavy" apache processes from the rest of the apache?

I.e. when the url is "/my_heavy_service" redirect the request to the apache which has the "heavy" application loaded, and the rest of the requests be handled by an apache with does not even has mod_rivet loaded?

Like starting an apache on a different port (i.e. 8123), which loads my application, and starting a "normal" apache on port 80, which serves all requests except some, which are directed to the server in port 8123.

In general I think it can be done (i.e.: http://wiki.apache.org/httpd/RunningMultipleApacheInstances),
but is a way to do this in fedora 19, and keep all this "systemctl * httpd" stuff?

Has anyone attempted this?

I am a bit confused about the mod_rewrite documentation. It shows this rule to block hotlinking:

RewriteCond "%{HTTP_REFERER}" "!^$"
RewriteCond "%{HTTP_REFERER}" "!www.example.com" [NC]
RewriteRule ".(gif|jpg|png)$" "-" [F,NC]

however, I'd think a better rule would be:

RewriteCond "%{HTTP_REFERER}" "^$" [OR]
RewriteCond "%{HTTP_REFERER}" "!(www.)?example.com/.*$" [OR,NC]
RewriteRule ".(gif|jpg|png)$" "-" [F,NC]

if I want to block anyone manually typing in a link (no referer) + hotlinking (probably has a referer). Do i need the [OR] on the 1st
RewriteCond and not the 2nd one? It seems to work with OR on both conditions.

I want to allow a directory " /var/www/html/ldap" to two users according to IPs (192.168.1.2 192.168.1.7):

 Order allow,deny
 Allow from 192.168.1.2 192.168.1.7
 Satisfy any
 AuthName "LDAP Authentication"
 AuthType Basic

 AuthBasicProvider ldap
 AuthzLDAPauthoritative off
 AuthLDAPURL ldap://192.168.1.3/dc=example,dc=com?uid?sub?(objectClass=*)
 Require valid-user

but I don't want to allow a sub directory to 192.168.1.7 (I want it to be allowed only to 192.168.1.2):

I have tried to add:

 Order allow,deny
 Allow from 192.168.1.2
 Satisfy any
 AuthName "LDAP Authentication"
 AuthType Basic

 AuthBasicProvider ldap
 AuthzLDAPauthoritative off
 AuthLDAPURL ldap://192.168.1.3/dc=example,dc=com?uid?sub?(objectClass=*)
 Require valid-user

but it seems that 192.168.1.7 can reach to manager directory because it is a part of ldap directory, how can I forbid this?
