Thanks for the information! Could you go into a little more detail with your first suggestion (the easiest). By stdin and stderr do you mean System.in and System.err in Java? Also is there anywhere I can find an examples of the code for this? For the helper and the squid.conf? Thanks, Edward. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Java-external-acl-tp3447049p3459035.html Sent from the Squid - Users mailing list archive at Nabble.com.
