Squid Allowing Sites Not In Any Allow List - Why?

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

 



Hello,
   
  I am having a problem with Squid allowing some
websites that are not 
in any of our allow list. For example, I can get to
Nike.com, but there 
is no such entry in any of my allow lists (not only
Nike.com, but 
approximately 15-25% of websites I try that are not on
either of the 
allow 
lists). I have looked around the FAQ and Googled the
problem, but have 
yet to find something similar. 
   
  Here are some specs/code:

  Running Squid 2.6STABLE9 on a M$ box (long story).
The users appear 
to authenticate correctly, and in a very limited way
Squid is 
functioning. After reading, I cannot find a similar
case where Squid is 
allowing 
things that don't exist in a allow list, and with this
small of a test 
ACL list/user group, I don't think it is an ACL
problem or confliction. 
   
  Any ideas or help would be greatly appreciated.
Thanks.
