RE: [squid-users] Web sites not fully loading because of Javascript?

Luis,

Big sites like that have content distribution networks. For those sites you need to find out where the majority of the content is hosted from.

ie: facebook.com hosts all of the content on fbcdn.net

same with myspace, etc...

Best,
Steven

So basically i only need to approve some other domains other than
.facebook.com .yahoo.com .weather.com in my whitelist???

Its hard for me to understand the relationship between having partial access
to a domain(s) and not being able to load the images correctly.

Currently I'm using whitelists only and leave the deny ALL option(by
default) in the squid.conf file.

Most of these are sites known to spread their contetn over multiple
domain names. I think you are blocking some of those names.

Have a look at the denials which have them as referer.
