cccc · 01-29-2009, 05:37 AM

hi

I have Squid Version 3.0 PRE5 installed on debian etch.
Howto exclude some URL from the proxy caching at squid.conf ?

I've added in squid.conf the following entries:

Code:

acl url dstdomain .mydomain.com
always_direct allow url
cache deny url

and hope is OK now.

Knows someone if I use

Code:

allow direct

for an URL in /etc/squid/squid.conf, do I need also an additional entry

Code:

cache deny

to exclude some domains from the proxy caching?

If i understand well you want to block a website, right?

you can create a file like bad-sites.acl where you will add all the sites or words (like sex) you want to block

Code:

intranet:/etc/squid3# cat bad-sites.acl
.meebo.com
.playboy.com

then add this line to your squid.conf

Code:

acl bad_url url_regex "/etc/squid3/bad-sites.acl"
http_access deny bad_url

No he does not.

He wants to disable the caching function.

Modify the squid configuration to this:

#no local caching
maximum_object_size 0 KB
minimum_object_size 0 KB

# specify uncachable requests
acl all src 0.0.0.0/0.0.0.0
no_cache deny all

# avoid having a cache directory
cache_dir null /tmp
or
cache_dir null /null

thx, but I'd like to exclude from the proxy caching just for some domains and not disable proxy caching generally.

I have a similar question - forgive me, my brain is completely blown atm, and I can't play about with the production server right now :P

Basically just want to exclude a particular part of a website from caching - I don't want to block the entire domain due to massive data issues, just one subdir (basically: staff bitching about PDFs)

acl NonCaching url_regex ^http://mydomain/subdir/downloads/$

Should work, yes?

You need to watch your regex syntax, need to scape the / characters, a quick google and found this thread, hopes it helps

Remember to back your squid.conf if you are changing it in your production environment and more if you are tired.

Code:

cat squid.conf > squid.conf.bak
