Subject Re: Question about the connection between Apache and Tomcat with JK
Date Thu, 23 Sep 2004 07:40:43 GMT
MT,

Many thanks for the prompt reply. I read into the document, however,
didn't find the answer to my question as following,

3. If using sockets, jdk 1.4 has only socket for TCP and UDP. But when
the apache and tomcat are deployed in the same machine, isn't it an
overhead to go down to the lower layers when sending data stream, and
go upwards when receiving data?


Any hint?

Kan
