public class Default
extends javax.servlet.http.HttpServlet

The default servlet. This servlet, normally mapped to /, provides the handling for static content, OPTION and TRACE methods for the context. The following initParameters are supported:

 
 acceptRanges If true, range requests and responses are supported
 
 dirAllowed If true, directory listings are returned if no welcome file is found. Else 403
 Forbidden.
 
 putAllowed If true, the PUT method is allowed
 
 delAllowed If true, the DELETE method is allowed
 
 redirectWelcome If true, welcome files are redirected rather than forwarded to.
 
 minGzipLength If set to a positive integer, then static content larger than this will be served
 as gzip content encoded if a matching resource is found ending with ".gz"
 
 resourceBase Set to replace the context resource base
 
 relativeResourceBase Set with a pathname relative to the base of the servlet context root. Useful
 for only serving static content out of only specific subdirectories.
 
 

The MOVE method is allowed if PUT and DELETE are allowed
