public class DefaultServlet extends javax.servlet.http.HttpServlet implements ResourceFactory
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.
welcomeServlets If true, attempt to dispatch to welcome files
that are servlets, but only after no matching static
resources could be found. If false, then a welcome
file must exist on disk. If "exact", then exact
servlet matches are supported without an existing file.
Default is true.
This must be false if you want directory listings,
but have index.jsp in your welcome file list.
redirectWelcome If true, welcome files are redirected rather than
forwarded to.
gzip If set to true, then static content will be served as
gzip content encoded if a matching resource is
found ending with ".gz"
resourceBase Set to replace the context resource base
resourceCache If set, this is a context attribute name, which the servlet
will use to look for a shared ResourceCache instance.
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.
pathInfoOnly If true, only the path info will be applied to the resourceBase
stylesheet Set with the location of an optional stylesheet that will be used
to decorate the directory listing html.
aliases If True, aliases of resources are allowed (eg. symbolic
links and caps variations). May bypass security constraints.
etags If True, weak etags will be handled.
maxCacheSize The maximum total size of the cache or 0 for no cache.
maxCachedFileSize The maximum size of a file to cache
maxCachedFiles The maximum number of files to cache
useFileMappedBuffer
If set to true, it will use mapped file buffer to serve static content
when using NIO connector. Setting this value to false means that
a direct buffer will be used instead of a mapped file buffer.
By default, this is set to true.
cacheControl If set, all static content will have this value set as the cache-control
header.

initContextHandler(javax.servlet.ServletContext servletContext)
Compute the field _contextHandler.
In the case where the DefaultServlet is deployed on the HttpService it is likely that this method needs to be overwritten to unwrap the ServletContext facade until we reach the original jetty's ContextHandler. |
