Re: [Exist-development] Added the option of checking server name for URL rewriting

[Loren C. <lor...@gm...>]

Hello Thomas,

The matching could be implemented by changing the following code in RewriteConfig.java:

                /*
                 * If the URLRewrite is a ControllerForward, then test to see if there is a condition
                 * on the server name.  If there is a condition on the server name and the names do not
                 * match, then ignore this ControllerForward.
                 */
                if (action instanceof ControllerForward) {
                	if (serverName != null) {
                		String controllerServerName = ((ControllerForward)action).getServerName();
                		if (controllerServerName != null) {
                			if (!serverName.equalsIgnoreCase(controllerServerName)) {
                				continue;
                			}
                		}
                	}
                	
                }

As for the access log file, that is specified in the Jetty config file.  

    <Ref id="RequestLog">
      <Set name="requestLog">
        <New id="RequestLogImpl" class="org.eclipse.jetty.server.NCSARequestLog">
          <Set name="filename"><SystemProperty name="jetty.home" default="."/>/logs/yyyy_mm_dd.request.log</Set>
          <Set name="filenameDateFormat">yyyy_MM_dd</Set>
          <Set name="retainDays">90</Set>
          <Set name="append">true</Set>
          <Set name="extended">true</Set>
          <Set name="logCookies">false</Set>
          <Set name="LogTimeZone">GMT</Set>
          <Set name="LogServer">true</Set>
        </New>
      </Set>
    </Ref>


The format of the logfile entries are as follows based on the parameters:

Extended

LogServer

Format

False

False

"%host %other %logname %time1 %methodurl %code %bytesd"

False

True

"%virtualname %host %other %logname %time1 %methodurl %code %bytesd"

True

False

"%host %other %logname %time1 %methodurl %code %bytesd %refererquot %uaquot"

True

True

"%virtualname %host %other %logname %time1 %methodurl %code %bytesd %refererquot %uaquot"

With the following being the legend: 


#   %virtualname      Web sever virtual hostname. Use this tag when same log
#                     contains data of several virtual web servers. AWStats
#                     will discard records not in SiteDomain nor HostAliases
#   %host             Client hostname or IP address (or Sender host for mail log)
#   %other            Means another not used field
#   %logname          Authenticated login/user with format: john
#   %time1            Date and time with format: [dd/mon/yyyy:hh:mm:ss +0000] or [dd/mon/yyyy:hh:mm:ss]
#   %methodurl        Method and URL with format: "GET /index.html HTTP/x.x"
#   %code             Return code status (with format for web log: 999)
#   %bytesd           Size of document in bytes
#   %refererquot      Referer page with format: "http://from.com/from.htm"
#   %uaquot           User agent with format: "Mozilla/4.0 (compatible, ...)"



You could write your own RequestLogger and have the server name mapped into the log file name.  I am planning on adding the JavaDoc to the NCSARequestLogger (https://bugs.eclipse.org/bugs/show_bug.cgi?id=302350) so that the impact of changing the parameter values is clear.
