National Squid service for CVMFS

If you are going to run jobs on your cluster using CernVM-FS you should also use squids to cache data at your site. In case you decide to not install a squid service at your site, Italian NGI provide a National squid service accessible only by registered italian sites.
Changed:

We have two squids with ACLs based source and destination. If you decide to use this service, please contact igi-noc@lists.italiangrid.it providing the network information of your WNs and the cvmfs server(s) your WNs need to contact.

We have two squids with ACLs based source and destination. If you decide to use this service, please contact igi-noc@lists.italiangrid.it providing:
  • the network information of your WNs (eg 131.154.101.0/255.255.255.0);
  • the cvmfs server(s) your WNs need to contact (eg: igi-cvmfs.cnaf.infn.it);
  • add the line CVMFS_HTTP_PROXY="http://squid01.cnaf.infn.it:3128|http://squid02.cnaf.infn.it:3128" to the configuration of the cvmfs client on each WN (usually under /etc/cvmfs/config.d/).

Eg. for VO igi.italiangrid.it.conf: /etc/cvmfs/config.d/igi.italiangrid.it.conf:CVMFS_HTTP_PROXY="http://squid01.cnaf.infn.it:3128|http://squid02.cnaf.infn.it:3128"
