[squid-users] Follow up question from Wiki... "how do I configure Squid not to cache a specific server?"
Hi Folks, I need a specific site to completely bypass my squid cache due to a broken external webapp. I have read the section "how do I configure Squid not to cache a specific server?" from the wiki, which I can implement with no issues, but what I am not sure is what this will actually do :) Will this allow traffic to pass through squid without caching it, or will this block the site for users?

[squid-users] Squid Cache and Load Balancing...
Hi Folks, I am looking at setting up two Linux-based caching servers for two WebMarshal servers for around 120 schools. The WebMarshal servers perform all the content checking and Squid will do all the caching. The two WebMarshal servers are using Windows load balancing so I would like to have a similar configuration for the Squid servers. I understand I can share the cache's between the two Squid servers and I have read around Pen, L7SW, LVS and keepalived but its not clear to me which bits I need to do what in the setup. Please can someone give me some pointers as to what I would need to get load balanced / HA Squid cache servers without buying a dedicated piece of load balancing hardware.

[squid-users] Opinions on Setup...
Hi Folks, A few weeks ago I posted a message on this list about setting up two squid-caching-only servers for two WebMarshal content-checking-only servers for around 120 school. I was pointed in the general direction by Amos and I have finally come to a configuration that may work and was hoping for some input. The squid servers will be on the same network, and running RedHat Linux Enterprise 5. I was then going to configure two CARP interfaces on them, e.g. 192.168.0.1 and 192.168.0.2. A single DNS entry for squid-proxy.domain.gov.uk will point to 192.168.0.1 and 192.168.0.2 and the squid cache's will be set up as cache_peer's of each other. Can anyone think of any issues I will have with this set up, or can anyone think of anything else that will help my setup?

[squid-users] CARP and Multicast...
Hi Folks, I posted to this list a few weeks ago, and have had time to get around to reading more of the squid manuals I have two identical Ubuntu Linux 6.06.2 LTS based Squid servers caching for two Web Marshal server front ends. The Web Marshal servers are load balanced using Windows Network Load Balancing (NLB) which gives redundancy and load balancing for the clients. I would now like to add some sort of redundancy and load balancing between the squid caches and would like to share the cache between the two servers. I think I want to set up my Squid's in a multicast group and then load balance between them using CARP. The two Squid's should be sibling-peers of each other. For example, cache_peer 224.9.9.9 multicast 3128 3130 ttl=64 #proxy icp #hostnametype port port options # - - --- cache_peer scache1 sibling 3128 3130 multicast-responder carp-load-factor=0.5 cache_peer scache2 sibling 3128 3130 multicast-responder carp-load-factor=0.5 Can anyone tell me if I am going in completely the wrong direction, or am I close to getting a redundant two-server setup with load balancing and shared caches?

[squid-users] Generated by question...
Hi Folks, I finally have a (temporary) Squid caching server up and running and am really impressed with it ☺ Thanks to all the developers. One thing I am trying to find out is if the “Generated by“ footer and the horizontal line can be completely removed using a configuration variable. I have altered the httpd_surppress_version_string to on, but I want to get rid of the footer completely. I have seen various posts about altering the code and re-compiling, but these posts were circa 2004, I was wondering if I am overlooking a variable I can use that has been introduced since then. I am running Squid 2.6 compiled with the following options: Squid Cache: Version 2.6.STABLE18 configure options: '--prefix=/usr' '--exec_prefix=/usr' '--bindir=/usr/sbin' '--sbindir=/usr/sbin' '--libexecdir=/usr/lib/squid' '--sysconfdir=/etc/squid' '--localstatedir=/var/spool/squid' '--datadir=/usr/share/squid' '--enable-async-io' '--with-pthreads' '--enable-storeio=ufs,aufs,coss,diskd,null' '--enable-linux-netfilter' '--enable-arp-acl' '--enable-epoll' '--enable-removal-policies=lru,heap' '--enable-snmp' '--enable-delay-pools' '--enable-htcp' '--enable-cache-digests' '--enable-underscores' '--enable-referer-log' '--enable-useragent-log' '--enable-auth=basic,digest,ntlm' '--enable-carp' '--enable-follow-x-forwarded-for' '--with-large-files' '--with-maxfd=65536' 'amd64-debian-linux' 'build_alias=amd64-debian-linux' 'host_alias=amd64-debian-linux' 'target_alias=amd64-debian-linux' 'CFLAGS=-Wall -g -O2' 'LDFLAGS=-Wl,-Bsymbolic-functions' 'CPPFLAGS=' Thanks, Andy McCall Senior Technical Officer -- ICT & Printing, The Unity Partnership... ...working with Oldham Metropolitan Borough Council Civic Centre West Street Oldham OL1 1UU -- Telephone: 0161 770 8814 Fax: 0161 770 3998 Email: [EMAIL PROTECTED] -- ** The information in this e-mail is confidential and may be legally privileged.

[squid-users] COSS and 1Gb files...
Hi Folks, Can anyone tell me if I am using coss for my cache will the -with-large-option allow me to set the max-size to 1048576 (1GB).

RE: [squid-users] Squid Error Pages
Hi Brie, I have just gone through a similar scenario myself. So I might be able to help. > I'm a longtime Squid user and I want to edit the error messages that > Squid provides. I've located the files (ERR_ACCESS_DENIED, > ERR_CACHE_ACCESS_DENIED, etc) and modified them but they are not > displayed as I thought. For example, Squid appends a line about itself You can get rid of the "Generated by.." signature by including the %s variable in your error page. As soon as you include the %s somewhere the page, "Generated by..." line no longer appears. This means that your error pages *must* include the word "squid" somewhere. If you want to hide it you can either alter the code and re-compile, or you could always change the colour of the text to match the background, for example: %s On a white background will allow you to hide the signature. You will still see "squid" if you look at the HTML source using your browser, but it's a quick fix if your not up to editing code. I believe that the FTP and Gopher signatures have to be removed by altering source and the above trick won't work. > and the cache manager and does not display some images even though the > HTML is correct. Like Henrik said, the images have to be served from a web server. > What is going on? I have Apache on the machine but I don't think that I am taking a guess that you have installed Apache, but put the images in the same folder as your error pages. That won't work. Put the images in your Apache root/htdocs/www folder. For example if you have a server called squid1.mydomain.com, and your htdocs folder is /var/www. Created a folder called images in there, and place all your images in /var/www/images. You should be able to see the images by visiting http://squid1.mydomain.com/images/yourimage.jpg in a browser. This is the same URL you would include in your ERR_ pages too. Finally, if you change the location of the error pages using the error_directory variable, don't forget to tell squid to pick up the change using squid -k reconfigure.

RE: [squid-users] FW: COSS and 1Gb files...
Thanks for the reply. I think I get it now. > There's no real benefit in using COSS for files greater than say, > 500kilobytes. > > At that point the seek'ing required to access data in the file becomes > more than the difference in overhead between COSS and normal UNIX > filesystems. > > Use COSS for small objects (under 500 odd kilobytes) and AUFS for > anything larger. Excellent. In that case the set up I put in place until I worked out how to get coss working is probably what I want anyway. One thing I wasn't sure on - Am I supposed to format my cache partition as aufs/ufs and specify aufs/ufs in squid.conf, or do I format it as ext2/ext3 and specify aufs/ufs in squid.conf? At the moment, I have a /cache as an ext2 file system and cache_dir ufs 4 16 256 in my squid.conf, which I think this is right. If that is right, what is the view on ext2 vs ext3 as the file system? Is the choice between slower access times, but quick recovery times using ext3, or quicker access times but slower recover times using ext2? 2008/7/13 Andy McCall <[EMAIL PROTECTED]>: > Sorry to re-post, the lack of replies means I am asking something that people > don't know, or I am asking something that isn't really related to squid. > > If I should be asking somewhere else please let me know. > > I basically want to use a 40GB COSS file store, but with an > maximum_object_size of 1048576 KB (1GB). > > -Original Message- > From: Andy McCall [mailto:[EMAIL PROTECTED] > Sent: 11 July 2008 16:58 > To: squid-users@squid-cache.org > Subject: [squid-users] COSS and 1Gb files... > > Hi Folks, > > Can anyone tell me if I am using coss for my cache will the > -with-large-option allow me to set the max-size to 1048576 (1GB). > > I have just realised the max object size was 1GB but coss was only allowing > 1MB files to be stored in the cache, causing me to only get around 1% disk > hit ratio. > > Thanks, > > Andy McCall > ** > The information in this e-mail is confidential and may be legally privileged. > It is intended solely for the addressee.

[squid-users] SSL Site Problem...
Hi Folks,
I have a problem accessing an SSL site through my Squid setup, IE just spins
its blue circle forever, and doesn't seem to ever actually time out. The same
site works when going direct. I have tried multiple browsers to eliminate the
browser as the issue.
Any help is appreciated, as I am really stuck now...

I contracted them to install and train me on Squid and the installation of Websense and they were excellent.

Thanks for >> the help! Also, wouldn't it be of some use caching high-use high-media sites in off-peak hours (00:00-04:30 in my case) so any new images are already cached for the morning? On the link I use we have almost no activity between 6PM and 8AM, but between 8AM-6PM its heavily in use, when I started reading this thread I thought pre-caching sites at around 4AM, like the BBC, Sky News etc. would be of some use. Yes, I know these sites get updated regularly during the day, but at least some of the new content would be already in the cache. Am I missing something?
