           Summary: Reply_timeout when recovery_options is larger than 1.
           Product: Tomcat 5
           Version: 5.0.28
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Native:JK
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: satout@intellilink.co.jp


Reply_timeout param told webserver to wait some time for reply to a forwarded 
request before considering the remote tomcat is dead and eventually switch to 
another tomcat in a cluster group.
But in the case of the network trouble processing the application program, the 
unconditional switch to another tomcat generates double registration of data.
To prevent this, when recovery_options is larger than 1, reply_timeout has to 
interrupt to switch to another tomcat and show the error page. 
Therefore, I made the following patches.
