Hello Amos, following your instructions I make this external_acl_type helper: #!/bin/bash result=`squidclient -h 192.168.19.19 mgr:active_requests | grep -c "$1"` if [ $result -eq 0 ] then echo 'OK' else echo 'ERR' fi # If I have the same URI then I denied. I make a few test and it work for me. The problem is when I add the rule to the squid. I make this: acl extensions url_regex "/etc/squid3/extensions" external_acl_type one_conn %URI /home/carlos/script acl limit external one_conn # where extensions have: \.(iso|avi|wav|mp3|mp4|mpeg|swf|flv|mpg|wma|ogg|wmv|asx|asf|deb|rpm|exe|zip|tar|tgz|rar|ppt|doc|tiff|pdf)$ http_access deny extensions limit So when I make squid3 -k reconfigure the squid stop working What can be happening ??? This is my log of squid: Mar 24 09:25:04 test squid[28075]: helperHandleRead: unexpected read from one_conn #1, 3 bytes 'OK ' Mar 24 09:25:04 test squid[28075]: helperHandleRead: unexpected read from one_conn #2, 3 bytes 'OK ' Mar 24 09:25:04 test squid[28075]: WARNING: one_conn #1 (FD 15) exited Mar 24 09:25:04 test squid[28075]: WARNING: one_conn #2 (FD 16) exited Mar 24 09:25:04 test squid[28075]: CACHEMGR: <unknown>@192.168.19.19 requesting 'active_requests' Mar 24 09:25:04 test squid[28075]: helperHandleRead: unexpected read from one_conn #3, 3 bytes 'OK ' Mar 24 09:25:04 test squid[28075]: WARNING: one_conn #3 (FD 24) exited Mar 24 09:25:04 test squid[28075]: helperHandleRead: unexpected read from one_conn #4, 4 bytes 'ERR ' Mar 24 09:25:04 test squid[28075]: WARNING: one_conn #4 (FD 27) exited Mar 24 09:25:04 test squid[28075]: Too few one_conn processes are running Mar 24 09:25:04 test squid[28075]: storeDirWriteCleanLogs: Starting...
