如何将 Java ICAP 编解码器与 Squid 一起使用
我正在尝试使用 Java ICAP Codec 1.0.0.GA Squid Echo 示例与 Squid 并得到以下异常
ch.mimo.netty.handler.codec.icap.IcapDecodingError: Mandatory ICAP message header [Encapsulated] is missing
at ch.mimo.netty.handler.codec.icap.ReadIcapHeaderState.validateMandatoryMessageHeaders(ReadIcapHeaderState.java:104)
at ch.mimo.netty.handler.codec.icap.ReadIcapHeaderState.execute(ReadIcapHeaderState.java:54)
at ch.mimo.netty.handler.codec.icap.IcapMessageDecoder.decode(IcapMessageDecoder.java:97)
at ch.mimo.netty.handler.codec.icap.IcapMessageDecoder.decode(IcapMessageDecoder.java:37)
at org.jboss.netty.handler.codec.replay.ReplayingDecoder.callDecode(ReplayingDecoder.java:470)
at org.jboss.netty.handler.codec.replay.ReplayingDecoder.messageReceived(ReplayingDecoder.java:443)
at org.jboss.netty.channel.Channels.fireMessageReceived(Channels.java:274)
这是我的 Squid 配置（与 ICAP 相关）：
icap_enable on
icap_service service_req reqmod_precache icap://127.0.0.1:1344
adaptation_access service_req allow all
有什么问题？

Here is my Squid config (related to ICAP):
icap_enable on
icap_service service_req reqmod_precache icap://127.0.0.1:1344
adaptation_access service_req allow all

众所周知，Squid 的 ICAP 客户端不会将封装标头添加到选项请求中。最新 1.0.0.GA 版本的 Java ICAP 编解码器 将处理选项和 100 个缺少封装标头的继续请求。
我建议您使用 Wireshark 转储网络流量并将其发布到此处。
Squid's ICAP client is known not to add an Encapsulated Header to Options requests. The latest 1.0.0.GA release of the Java ICAP Codec will handle Options, and 100 Continue requests with missing Encapsulated headers.
I suggest you dump the network traffic with Wireshark and post it here.
