Jetty 12.0.6 · org.eclipse.jetty.ee10.servlet.DefaultServlet

The default Servlet, normally mapped to /, that handles static resources.

The following init parameters are supported:

acceptRanges: Use true to accept range requests, defaults to true.
baseResource: Defaults to the context's baseResource. The root directory to look for static resources.
cacheControl: The value of the Cache-Control header. If omitted, no Cache-Control header is generated in responses. By default is omitted.
cacheValidationTime: How long in milliseconds a resource is cached. If omitted, defaults to 1000 ms. Use -1 to cache forever or 0 to not cache.
dirAllowed: Use true to serve directory listing if no welcome file is found. Otherwise responds with 403 Forbidden. Defaults to true.
encodingHeaderCacheSize: Max number of cached Accept-Encoding entries. Use -1 for the default value (100), 0 for no cache.
etags: Use true to generate ETags in responses. Defaults to false.
maxCachedFiles: The max number of cached static resources. Use -1 for the default value (2048) or 0 for no cache.
maxCachedFileSize: The max size in bytes of a single cached static resource. Use -1 for the default value (128 MiB) or 0 for no cache.
maxCacheSize: The max size in bytes of the cache for static resources. Use -1 for the default value (256 MiB) or 0 for no cache.
otherGzipFileExtensions: A comma-separated list of extensions of files whose content is implicitly gzipped. Defaults to .svgz.
precompressed: Omitted by default, so that no pre-compressed content will be served. If set to true, the default set of pre-compressed formats will be used. Otherwise can be set to a comma-separated list of encoding=extension pairs, such as: br=.br,gzip=.gz,bzip2=.bz, where encoding is used as the value for the Content-Encoding header.
redirectWelcome: Use true to redirect welcome files, otherwise they are forwarded. Defaults to false.
stylesheet: Defaults to the Server's default stylesheet, jetty-dir.css. The path of a custom stylesheet to style the directory listing HTML.
useFileMappedBuffer: Use true to use file mapping to serve static resources. Defaults to false.
welcomeServlets: Use false to only serve welcome resources from the file system. Use true to dispatch welcome resources to a matching Servlet (for example mapped to *.welcome), when the welcome resources does not exist on file system. Use exact to dispatch welcome resource to a Servlet whose mapping is exactly the same as the welcome resource (for example /index.welcome), when the welcome resources does not exist on file system. Defaults to false.

Called by the server (via the `service` method) to allow a servlet to handle a GET request.
protected void	doHead(HttpServletRequest the request object that is passed to the servlet req, HttpServletResponse the response object that the servlet uses to return the headers to the clien resp) Overrides jakarta.servlet.http.HttpServlet.doHead. Receives an HTTP HEAD request from the protected `service` method and handles the request.
protected void	doOptions(HttpServletRequest the `HttpServletRequest` object that contains the request the client made of the servlet req, HttpServletResponse the `HttpServletResponse` object that contains the response the servlet returns to the client resp) Overrides jakarta.servlet.http.HttpServlet.doOptions. Called by the server (via the `service` method) to allow a servlet to handle a OPTIONS request.
protected void	doTrace(HttpServletRequest the `HttpServletRequest` object that contains the request the client made of the servlet req, HttpServletResponse the `HttpServletResponse` object that contains the response the servlet returns to the client resp) Overrides jakarta.servlet.http.HttpServlet.doTrace. Called by the server (via the `service` method) to allow a servlet to handle a TRACE request.

public String	Returns: a `String` containing the value of the initialization parameter getInitParameter(String a `String` specifying the name of the initialization parameter name) Overrides jakarta.servlet.GenericServlet.getInitParameter. Implements jakarta.servlet.ServletConfig.getInitParameter. Returns a `String` containing the value of the named initialization parameter, or null if the parameter does not exist.
private Resource	getResource(URI uri)
