[Q]: CoyoteRequest implements HttpRequest, HttpServletRequest versus Request, ServletRequest

2002-09-26 Thread Francis ANDRE 

Hi

I am a newbe with Tomcat and I am wondering why

CoyoteRequest implements org.apache.catalina.HttpRequest and
javax.servlet.http.HttpServletRequest
and not
CoyoteRequest implements org.apache.catalina.Requestand
javax.servlet.ServletRequest.


I would have made 2 subclasses to avoid the specialisation of CoyoteRequest
over http

CoyoteRequest implements
org.apache.catalina.Requestand javax.servlet.ServletRequest.
CoyoteHttpRequest extends CoyoteRequest implements
org.apache.catalina.HttpRequest and javax.servlet.http.ServletRequest.


Any idea??


Regards
