public class DefaultServlet extends 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. 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 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. aliases If True, aliases of resources are allowed (eg. symbolic links and caps variations). May bypass security constraints. 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 cacheType Set to "bio", "nio" or "both" to determine the type resource cache. A bio cached buffer may be used by nio but is not as efficient as an nio buffer. An nio cached buffer may not be used by bio. 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.
