[squid-users] SQUID syslog to rsyslog server (v2.7 Windows)

[Full Name]

We've added in the two lines below to the 'squid.conf' file and restarted the service, but syslog traffic does not appear to be currently flowing:
(The hashed out line was what was previously being used with data successfully being logged to a local file.)

   access_log udp://10.203.193.25:514 squid
   access_log syslog:local0.info squid
   #access_log c:/ClientSiteProxy/var/logs/Access.log

Are these the correct command directives and in the correct format?

There is reference to there being a syslog 'facility' which we've arbitrarily picked 'local0'  However cannot find anything in the reference that states the meaning of each of the facility options.

Thanks in advance
