@Adnan Shahzad-2: I don't immediately see that this has anything to do with external acl helpers. I am not a squid expert, but I think if you want to accept all requests for http://irqa-pc/, then you could define an acl with acl irqa-pc url_regex ^http://irqa-pc/ and put http_access allow irqa-pc early on in the http_access section of the config file. If you want to accept requests to any URL with no dots in the domain component then you could probably use acl no_dots url_regex ^http://[^.]*/ http_access allow no_dots Others might be able to help with why you are getting so many requests for this destination -- perhaps start a new thread? -- View this message in context: http://n4.nabble.com/Trouble-writing-external-acl-helper-tp1839464p1866336.html Sent from the Squid - Users mailing list archive at Nabble.com.
