Subject cvs commit: jakarta-tomcat-connectors/jk/native2/common jk_channel.c
Date Sun, 26 May 2002 07:33:49 GMT

  Added:       jk/native2/common jk_channel.c
  Log:
  Common dispatcher for all channels - allow any jk channel to be called by
  the JNI code.
  
  This is not yet completed, but will reduce the work in 1/2, since the
  same code will be used on both sides and optimizations will be shared
  by all components.
  
  I hope to see in few months at least a doors channel, and maybe play
  with message queues and some windows-specific things - just for the fun
  of doing a small benchmark.
