cache_object// showing miss should not cache the loopback right?

[mcury]

@JonathanLee Are you monitoring squid with a 3rd party app ? Perhaps sarge, lightsquid or sqstat ?
Try disabling it for a moment to see if it goes away.

@mcury light squid can it see that and try to cache that? Should I add a bypass in light squid?

I suppose lightsquid is checking cache status only.
First I would make sure it is lightsquid generating those logs, if you can, disable for a few minutes to see if those logs disappear.

According to this post:

You can try this:

acl exclude dst localhost
access_log none exclude

@mcury ok it is doing this in there a way to resolve this? Bypass local host on squidguard?

I always bypassed these networks from the proxy, perhaps you should, unfortunately there is a long time I don't use squid, so give it a shot to see how it goes.

   isInNet(dnsResolve(host), "10.0.0.0",  "255.0.0.0") ||
    isInNet(dnsResolve(host), "172.16.0.0",  "255.240.0.0") ||
    isInNet(dnsResolve(host), "192.168.0.0",  "255.255.0.0") ||
    isInNet(dnsResolve(host), "127.0.0.0", "255.0.0.0") ||

@mcury thanks where are you adding this information into the WPAD? DNS entries.

I wouldn't use WPAD because I can't update the .pac file on the fly.
I used to deploy .pac file directly to the browsers, using a setting to do not cache .pac file using GPO.
So, when a new bypass was required, I would update the .pac file and ask the user to close and reopen the browser to get the newest thing.
I also used to set "do not allow the user to change proxy settings".

For smartphones, I would put them in another VLAN and leave them alone, sometimes some DNS filtering only depending on the environment.

@mcury

Is this where the ACL should go?

[JonathanLee]

@mcury

More thought this would be a better solution right outside of just not logging it?

Except http access deny at the end of the list

[mcury]

@JonathanLee To be honest, I'm not sure what is best, a lot things about squid I forgot..
I have a few .txt files here stored from years ago but that is it..

[JonathanLee]

@mcury I think I found the solution..

or just add loopback to splice only so it stops accessing miss_access or acl for it

testing this

http://www.squid-cache.org/Doc/config/acl/
http://www.squid-cache.org/Doc/code/AnnotateClient_8h.dyn

[JonathanLee]

I am going to test this without use of splice the loopback. I removed it from my non bump

Per Squid Docs...

acl aclname annotate_client [-m[=delimiters]] key=value ...
	acl aclname annotate_client [-m[=delimiters]] key+=value ...
	  #
	  # Always matches. [fast]
	  # Used for its side effect: This ACL immediately adds a
	  # key=value annotation to the current client-to-Squid
	  # connection. Connection annotations are propagated to the current
	  # and all future master transactions on the annotated connection.
	  # See the annotate_transaction ACL for details.
	  #
	  # For example, the following configuration avoids rewriting URLs
	  # of transactions bumped by SslBump:
	  #
	  #  # First, mark bumped connections:
	  #  acl markBumped annotate_client bumped=true
	  #  ssl_bump peek acl1
	  #  ssl_bump stare acl2
	  #  ssl_bump bump acl3 markBumped
	  #  ssl_bump splice all
	  #
	  #  # Second, do not send marked transactions to the redirector:
	  #  acl markedBumped note bumped true
	  #  url_rewrite_access deny markedBumped
	  #
	  #  # Note that the following would not have worked because acl3 alone
	  #  # does not determine whether the connection is going to be bumped:
	  #  url_rewrite_access deny acl3 # Wrong!

@JonathanLee

Now I got some improved hits!!! WOW

[mcury]

@JonathanLee ow, good to hear that
