톰캣 Connector 프로토콜 설정

<Connector protocol="org.apache.coyote.http11.Http11AprProtocol"  ..>

현재 톰캣은 아래의 6가지의 Connector protocol이 있다. 

org.apache.coyote.http11.Http11Protocol

org.apache.coyote.http11.Http11NioProtocol

org.apache.coyote.http11.Http11AprProtocol

org.apache.coyote.ajp.AjpProtocol

org.apache.coyote.ajp.AjpAprProtocol

org.apache.jk.server.JkCoyoteHandler (protocol보다는 jk handler인데, 광의차원에서 protocol로 넣어준다)

톰캐 5.5부터 자세한 내용을 본다..

톰캣 5.5 

connector 가 http일 때,

http://tomcat.apache.org/tomcat-5.5-doc/config/http.html

protocol : This attribute value must be HTTP/1.1 to use the HTTP handler, which is the default.

connector가 ajp일 때,

http://tomcat.apache.org/tomcat-5.5-doc/config/ajp.html

protocol : This attribute value must be AJP/1.3 to use the AJP handler.

톰캣 5.5에서는 

ajp/1.3은 org.apache.jk.server.JkCoyoteHandler를 의미하고, http 1.1 protocol에서는 org.apache.coyote.http11.Http11Protocol를 사용하였다.

Tomcat 6

connector 가 http일 때,

http://tomcat.apache.org/tomcat-6.0-doc/config/http.html

protocol

Sets the protocol to handle incoming traffic. The default value is HTTP/1.1 and configures the org.apache.coyote.http11.Http11Protocol. This is the blocking Java connector.

If the PATH(Windows) or LD_LIBRARY_PATH(on most unix system) environment variables contain the Tomcat native library, the APR connector will automatically be configured. Please be advised that the APR connector has different settings for HTTPS than the default Java connector.

Other values for this attribute are, but not limited to:

org.apache.coyote.http11.Http11Protocol - same as HTTP/1.1

org.apache.coyote.http11.Http11NioProtocol - non blocking Java connector

org.apache.coyote.http11.Http11AprProtocol - the APR connector.

Take a look at our Connector Comparison chart. The configuration for both Java connectors are identical, both for http and https. 

For more information on the APR connector and APR specific SSL settings please visit the APR documentation

connector가 ajp일 때,

http://tomcat.apache.org/tomcat-6.0-doc/config/ajp.html

protocol

Sets the protocol to handle incoming traffic. The default value is AJP/1.3 and configures org.apache.jk.server.JkCoyoteHandler the original blocking Java connector by default.

If the PATH (Windows) or LD_LIBRARY_PATH (on most unix systems) environment variables contain the Tomcat native library, the native/APR connector will automatically be configured instead.

To use an explicit protocol rather than rely on the auto-switching mechanism described above, the following values may be used:

org.apache.jk.server.JkCoyoteHandler - original blocking Java connector

org.apache.coyote.ajp.AjpProtocol - new blocking Java connector that supports an executor

org.apache.coyote.ajp.AjpAprProtocol - the APR/native connector.

Custom implementations may also be used.

내가 보통 쓰는 방법은 세가지였다..

1) 아파치와 연동하는 것

    <!-- Define an AJP 1.3 Connector on port 8009 -->

    <Connector port="8009" 

               enableLookups="false" redirectPort="8443" protocol="AJP/1.3" URIEncoding="UTF-8"/>

2) 직접 요청을 받아서 처리하는 것

    <!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->

    <Connector port="8080" maxHttpHeaderSize="8192"

               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"

               enableLookups="false" redirectPort="8443" acceptCount="100"

               connectionTimeout="20000" disableUploadTimeout="true" URIEncoding="UTF-8"/>

3) comet을 이용하는 것

<connector connectiontimeout="20000" port="8000">

     protocol="org.apache.coyote.http11.Http11NioProtocol" useComet="true" redirectPort="8443"/>

공부를 하기 위한 좋은 내용이 있어서 소개한다.

Connector Comparison

Below is a small chart that shows how the connectors differentiate.

Http 11NioProtocol 공부를 많이 해야겠다는 생각이 든다..

comet 공부 시작해보자~
