    This class is logback's implementation of jetty's RequestLog interface.

    It can be seen as logback classic's LoggerContext. Appenders can be attached directly to RequestLogImpl and RequestLogImpl uses the same StatusManager as LoggerContext does. It also provides containers for properties.

    Supported Jetty Versions

    This RequestLogImpl only supports Jetty 7.0.0 through Jetty 10. If you are using Jetty 11 with the new Jakarta Servlets (namespace jakarta.servlet) then you will need a more modern version of logback-access.

    Configuring for Jetty 9.4.x through to Jetty 10.0.x

    Jetty 9.4.x and Jetty 10.x use a modern @{code server.setRequestLog(RequestLog)} interface that is based on a Server level RequestLog behavior. This means all requests are logged, even bad requests, and context-less requests. The internals of the Jetty Request and Response objects track the state of the object at the time they are committed (the actual state during the application when an action on the network commits the request/response exchange). This prevents behaviors from 3rd party libraries that change the state of the request / response before the RequestLog gets a chance to log the details. This differs from Jetty 9.3.x and older in that those versions used a (now deprecated) RequestLogHandler and would never see bad requests, or context-less requests, and if a 3rd party library modifies the the response (for example by setting response.setStatus(200) after the response has been initiated on the network) this change in status would be logged, instead of the actual status that was sent.

    First, you must be using the proper ${jetty.home} and ${jetty.base} directory split. Configure your ${jetty.base} with at least the `resources` module enabled (so that your configuration can be found).

    Next, create a ${jetty.base}/etc/logback-access-requestlog.xml file with the following content. 

       <?xml version="1.0"?>
   <!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_3.dtd">

   <Configure id="Server" class="org.eclipse.jetty.server.Server">
     <Set name="requestLog">
       <New id="LogbackAccess" class="ch.qos.logback.access.jetty.RequestLogImpl">
         <Set name="resource">logback-access.xml</Set>
       </New>
     </Set>
   </Configure>

    Now you'll need a ${jetty.base}/resources/logback-access.xml configuration file.

    By default, RequestLogImpl looks for a logback configuration file called etc/logback-access.xml, in the ${jetty.base} directory, then the older ${jetty.home} directory. The logback-access.xml file is slightly different than the usual logback classic configuration file. Most of it is the same: Appenders and Layouts are declared the exact same way. However, loggers elements are not allowed.

    It is possible to put the logback configuration file anywhere, as long as it's path is specified. Here is another example, with a path to the logback-access.xml file. 

       <?xml version="1.0"?>
   <!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_3.dtd">

   <Configure id="Server" class="org.eclipse.jetty.server.Server">
     <Set name="requestLog">
       <New id="LogbackAccess" class="ch.qos.logback.access.jetty.RequestLogImpl">
         <Set name="fileName">/path/to/logback-access.xml</Set>
       </New>
     </Set>
   </Configure>

    Configuring for Jetty 7.x thru to Jetty 9.3.x

    To configure these older Jetty instances to use RequestLogImpl, the use of the RequestLogHandler is the technique available to you. Modify your etc/jetty-requestlog.xml 

       <?xml version="1.0"?>
   <!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">

   <Configure id="Server" class="org.eclipse.jetty.server.Server">
     <Ref id="Handlers">
       <Call name="addHandler">
         <Arg>
           <New id="RequestLog" class="org.eclipse.jetty.server.handler.RequestLogHandler">
             <Set name="requestLog">
               <New id="RequestLogImpl" class="ch.qos.logback.access.jetty.RequestLogImpl"/>
             </Set>
           </New>
         </Arg>
       </Call>
     </Ref>
   </Configure>

    By default, RequestLogImpl looks for a logback configuration file called logback-access.xml, in the same folder where jetty.xml is located, that is etc/logback-access.xml. The logback-access.xml file is slightly different than the usual logback classic configuration file. Most of it is the same: Appenders and Layouts are declared the exact same way. However, loggers elements are not allowed.

    It is possible to put the logback configuration file anywhere, as long as it's path is specified. Here is another example, with a path to the logback-access.xml file. 

       <?xml version="1.0"?>
   <!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">

   <Configure id="Server" class="org.eclipse.jetty.server.Server">
     <Ref id="Handlers">
       <Call name="addHandler">
         <Arg>
           <New id="RequestLog" class="org.eclipse.jetty.server.handler.RequestLogHandler">
             <Set name="requestLog">
               <New id="RequestLogImpl" class="ch.qos.logback.access.jetty.RequestLogImpl">
                 <Set name="fileName">path/to/logback-access.xml</Set>
               </New>
             </Set>
           </New>
         </Arg>
       </Call>
     </Ref>
   </Configure>

    Here is a sample logback-access.xml file that can be used right away: 

        <configuration>
      <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.access.PatternLayout">
          <param name="Pattern" value="%date %server %remoteIP %clientHost %user %requestURL" />
        </layout>
      </appender>

      <appender-ref ref="STDOUT" />
    </configuration>

    Another configuration file, using SMTPAppender, could be: 

        <configuration>
      <appender name="SMTP" class="ch.qos.logback.access.net.SMTPAppender">
        <layout class="ch.qos.logback.access.PatternLayout">
          <param name="pattern" value="%remoteIP [%date] %requestURL %statusCode %bytesSent" />
        </layout>
        <param name="From" value="sender@domaine.org" />
        <param name="SMTPHost" value="mail.domain.org" />
         <param name="Subject" value="Last Event: %statusCode %requestURL" />
         <param name="To" value="server_admin@domain.org" />
      </appender>
      <appender-ref ref="SMTP" />
    </configuration>
