Regarding url_regex acl

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Dear Team,

I am using squid proxy 3.1 in centos machine. I want to restrict
client request from particular domain and web context.

 #
# Recommended minimum configuration:
#
acl manager proto cache_object
acl localhost src 127.0.0.1/32 ::1
acl to_localhost dst 127.0.0.0/8 ::1

acl urlwhitelist url_regex -i ^http(s)://([a-zA-Z]+).zmedia.com/blog/.*$
acl allowdomain dstdomain .zmedia.com

acl Safe_ports port 80 8080 8500 7272
# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed

acl SSL_ports port 443
acl Safe_ports port 80      # http
acl Safe_ports port 21      # ftp
acl Safe_ports port 443     # https
acl Safe_ports port 70      # gopher
acl Safe_ports port 210     # wais
acl Safe_ports port 1025-65535  # unregistered ports
acl Safe_ports port 280     # http-mgmt
acl Safe_ports port 488     # gss-http
acl Safe_ports port 591     # filemaker
acl Safe_ports port 777     # multiling http
acl SSL_ports  port 7272        # multiling http
acl CONNECT method CONNECT

#
# Recommended minimum Access Permission configuration:
#
# Only allow cachemgr access from localhost
http_access allow manager localhost
http_access deny manager
http_access deny !allowdomain
http_access allow urlwhitelist
http_access allow CONNECT SSL_ports
http_access deny CONNECT !SSL_ports
# Deny requests to certain unsafe ports
http_access deny !Safe_ports

# Deny CONNECT to other than secure SSL ports
http_access deny CONNECT !SSL_ports


# We strongly recommend the following be uncommented to protect innocent
# web applications running on the proxy server who think the only
# one who can access services on "localhost" is a local user
#http_access deny to_localhost

#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#

# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks
# from where browsing should be allowed
http_access allow localhost

# And finally deny all other access to this proxy
http_access deny all

# Squid normally listens to port 3128
http_port 3128

# We recommend you to use at least the following line.
hierarchy_stoplist cgi-bin ?

# Uncomment and adjust the following to add a disk cache directory.
#cache_dir ufs /var/spool/squid 100 16 256

# Leave coredumps in the first cache dir
coredump_dir /var/spool/squid
append_domain .zmedia.com

# Add any of your own refresh_pattern entries above these.
refresh_pattern ^ftp:       1440    20% 10080
refresh_pattern ^gopher:    1440    0%  1440
refresh_pattern -i (/cgi-bin/|\?) 0 0%  0
refresh_pattern .       0   20% 4320

What am I trying here is?

Restrict request only from(.zmedia.com) and it's working fine. But , I
can able to access request from any context (url_regex  not working).

URLS Should be allowed.

https://accounts.zmedia.com/blog/aboutusers.html
https://contacts.zmedia.com/blog/aboutusers.html
https://shop.zmedia.com/blog/aboutusers.html
...

URLS Should not be allowed

https://shop.zmedia.com/admin/aboutusers.html

But , now I can able to access(https://shop.zmedia.com/admin/aboutusers.html) .

Bharathikannan R
