cvs commit: jakarta-tomcat/src/share/org/apache/tomcat/service/http HttpRequestAdapter.java HttpResponseAdapter.java HttpConnectionHandler.java HttpResponse.java HttpServletIS.java HttpServletOS.java

costin      99/11/01 14:24:33

  Modified:    src/share/org/apache/tomcat/server HttpResponseAdapter.java
               src/share/org/apache/tomcat/service
                        Ajp11ConnectionHandler.java
               src/share/org/apache/tomcat/service/connector
                        Ajp12ConnectionHandler.java
               src/share/org/apache/tomcat/service/http
                        HttpConnectionHandler.java
  Added:       src/share/org/apache/tomcat/service/http
                        HttpRequestAdapter.java HttpResponseAdapter.java
  Removed:     src/share/org/apache/tomcat/service/http HttpResponse.java
                        HttpServletIS.java HttpServletOS.java
  Log:
  -Ajp11 and Ajp12 converted to ResponseAdapter
  -HttpResponse/Request adapter moved to tomcat.service.http ( the new
  Http adapter )
  -Removed old HttpResponse/Request and Input/Output stream ( now the Http
  adapter uses only adapter interfaces )
