No, that's not how this proxying service work. You have to enter the correct combination of hostname and port number to get access. Everytime i use a new account to try their service, i get a new proxy address (eg,3121212.proxy.com) and a port number(in the range of 30000). it's not the listening port. i used their service on my phone, and all i have to do is to enter the proxy address and port number in network setting in my android phone,then almost all internet traffic are routed through the proxy. no authentication windows pops up when i browser the internet. when i goes to a incorrect domain, the squid standard error page will display, and that's when i know they are using squid. I'm not sure if there are other software involved in this. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/how-to-implement-access-control-using-connetcing-hostname-and-port-tp4666818p4666835.html Sent from the Squid - Users mailing list archive at Nabble.com.
