[squid-users] connection limit and X-Forwarded-For IP

Hi All,

Recently I configure Squid as reverse proxy for back-end apache server
running Drupal.

acl airarabia_web dstdomain www.airarabia.com
cache_peer 10.4.171.6 parent 80 0 no-query originserver
name=airarabia_peer2 round-robin forceddomain=www.airarabia.com default
# cache_peer 10.4.171.7 parent 80 0 no-query originserver
name=airarabia_peer1 round-robin forceddomain=www.airarabia.com default
# not yet implemented
cache_peer_access airarabia_peer2 allow airarabia_web
cache_peer_access airarabia_peer2 deny all

Problem 1:-
With Apache I had connection Limit of 20 per IP (mod_limitipconn.so)

I need to achieve this with squid reverse proxy.
please let me know if below configurations is correct.

===========================
acl connectionLimit maxconn 20
acl airarabia_web dstdomain www.airarabia.com
cache_peer 10.4.171.6 parent 80 0 no-query originserver
name=airarabia_peer2 round-robin forceddomain=www.airarabia.com default
cache_peer_access airarabia_peer2 allow airarabia_web connectionLimit
cache_peer_access airarabia_peer2 deny all
===========================

Problem 2:-
After configuring reverse proxy, The apache back-end server gets the IP
of the reverse proxy and not of the actual clients.

                    squid.conf
===========================
follow_x_forwarded_for allow airarabia_web
follow_x_forwarded_for deny all
acl_uses_indirect_client on
delay_pool_uses_indirect_client on
log_uses_indirect_client on
===========================

I will work on HOW TO for mod_extract_forwarded, but mean time if
someone can verify if the above squid.conf for problem 2 is correct?
