Q&A
Illegal character in hostname;
だそうですが、
visible_hostname unknownとか
危なさそうに思えますが、どうでしょう？
うちもかつてsqid運用してましたが、
こんなことはわざわざ書いた覚えが無いです。
前提・実現したいこと
amazon linuxでのsquidを使用してプロキシサーバーの構築を行いたい。

試したこと
tcp_outgoing_address にはEC2のセカンダリプライベートIPを記述しています。 http_portにはeth0で許可したポートを記述しています。
ネットで情報を探しているのですが情報が出てこなく困っています。ご教授お願いいたします。
> The following error was encountered while trying to retrieve the URL: /
URLのところに何も入っていませんが、どのようにアクセスしたんでしょうか？
何をしたらこのエラーが発生したのかをなるべく具体的に書いてください。
あと、squidのログファイルにはなにか出ていませんか？
