Subject cvs commit: jakarta-tomcat-connectors/http11/src/java/org/apache/coyote/http11 Http11Processor.java
Date Tue, 29 Jul 2003 18:53:20 GMT
remm        2003/07/29 11:53:20

  Modified:    http11/src/java/org/apache/coyote/http11
                        Http11Processor.java
  Log:
  - Reduce timeout and disable keepalive when the server starts running out
    or processors (of course, if servlet processing times are too long, or is under
    a DoS attack, it might still run out of processors).
  - The policy is really simple, and could obviously be tweaked (and a flag can
    be added to make it optional, etc).
