Remarks
Recall these are commands that Tomcat generates to configure Apache.
As the first comments indicates, these commands relate to the servlet context called dbc/.
The Alias command causes Apache to generally look in the Tomcat document directory for URLs with paths that start /dbc.
- This is needed for static documents in the Tomcat directory.
The first JkMount command causes URLs with paths that match the pattern /dbc/servlet/* to be redirected to the AJP module (hence the Tomcat server).
The second JkMount command causes URLs with paths that match the pattern /dbc/*.jsp to be similarly redirected Tomcat server.
