  • Field Details

  • Constructor Details

    • CoyoteAdapter

      public CoyoteAdapter(Connector connector)
      Construct a new CoyoteProcessor associated with the specified connector.
      Parameters:
      connector - CoyoteConnector that owns this processor

  • Method Details

    • asyncDispatch

      public boolean asyncDispatch(Request req, Response res, SocketEvent status) throws Exception
      Description copied from interface: Adapter
      Dispatch asynchronous event.
      Specified by:
      asyncDispatch in interface Adapter
      Parameters:
      req - the request object
      res - the response object
      status - the event being processed
      Returns:
      true if the dispatch was successful
      Throws:
      Exception - If the processing fails unexpectedly

    • service

      public void service(Request req, Response res) throws Exception
      Description copied from interface: Adapter
      Call the service method, and notify all listeners.
      Specified by:
      service in interface Adapter
      Parameters:
      req - The request object
      res - The response object
      Throws:
      Exception - if an error happens during handling of the request. Common errors are:
      • IOException if an input/output error occurs and we are processing an included servlet (otherwise it is swallowed and handled by the top level error handler mechanism)
      • ServletException if a servlet throws an exception and we are processing an included servlet (otherwise it is swallowed and handled by the top level error handler mechanism)
      Tomcat should be able to handle and log any other exception ( including runtime exceptions )

    • prepare

      public boolean prepare(Request req, Response res) throws IOException, ServletException
      Description copied from interface: Adapter
      Prepare the given request/response for processing. This method requires that the request object has been populated with the information available from the HTTP headers.
      Specified by:
      prepare in interface Adapter
      Parameters:
      req - The request object
      res - The response object
      Returns:
      true if processing can continue, otherwise false in which case an appropriate error will have been set on the response
      Throws:
      IOException
      ServletException

    • log

      public void log(Request req, Response res, long time)
      Description copied from interface: Adapter
      Callback to allow logging access outside of the execution of the regular service.
      Specified by:
      log in interface Adapter
      Parameters:
      req - the request object
      res - the response object
      time - time taken to process the request/response in milliseconds (use 0 if not known)

    • checkRecycled

      public void checkRecycled(Request req, Response res)
      Description copied from interface: Adapter
      Assert that request and response have been recycled. If they have not then log a warning and force a recycle. This method is called as a safety check when a processor is being recycled and may be returned to a pool for reuse.
      Specified by:
      checkRecycled in interface Adapter
      Parameters:
      req - Request
      res - Response

    • getDomain

      public String getDomain()
      Description copied from interface: Adapter
      Provide the name of the domain to use to register MBeans for components associated with the connector.
      Specified by:
      getDomain in interface Adapter
      Returns:
      The MBean domain name

    • postParseRequest

      protected boolean postParseRequest(Request req, Request request, Response res, Response response) throws IOException, ServletException
      Perform the necessary processing after the HTTP headers have been parsed to enable the request/response pair to be passed to the start of the container pipeline for processing.
      Parameters:
      req - The coyote request object
      request - The catalina request object
      res - The coyote response object
      response - The catalina response object
      Returns:
      true if the request should be passed on to the start of the container pipeline, otherwise false
      Throws:
      IOException - If there is insufficient space in a buffer while processing headers
      ServletException - If the supported methods of the target servlet cannot be determined

    • parsePathParameters

      protected void parsePathParameters(Request req, Request request)
      Extract the path parameters from the request. This assumes parameters are of the form /path;name=value;name2=value2/ etc. Currently only really interested in the session ID that will be in this form. Other parameters can safely be ignored.
      Parameters:
      req - The Coyote request object
      request - The Servlet request object

    • parseSessionSslId

      protected void parseSessionSslId(Request request)
      Look for SSL session ID if required. Only look for SSL Session ID if it is the only tracking method enabled.
      Parameters:
      request - The Servlet request object

    • parseSessionCookiesId

      protected void parseSessionCookiesId(Request request)
      Parse session id in Cookie.
      Parameters:
      request - The Servlet request object

    • convertURI

      protected void convertURI(MessageBytes uri, Request request) throws IOException
      Character conversion of the URI.
      Parameters:
      uri - MessageBytes object containing the URI
      request - The Servlet request object
      Throws:
      IOException - if a IO exception occurs sending an error to the client

    • convertMB

      protected void convertMB(MessageBytes mb)
      Character conversion of the a US-ASCII MessageBytes.
      Parameters:
      mb - The MessageBytes instance containing the bytes that should be converted to chars

    • normalize

      public static boolean normalize(MessageBytes uriMB, boolean allowBackslash)
      This method normalizes "\", "//", "/./" and "/../".
      Parameters:
      uriMB - URI to be normalized
      allowBackslash - true if backslash characters are allowed in URLs
      Returns:
      false if normalizing this URI would require going above the root, or if the URI contains a null byte, otherwise true

    • copyBytes

      protected static void copyBytes(byte[] b, int dest, int src, int len)
      Copy an array of bytes to a different position. Used during normalization.
      Parameters:
      b - The bytes that should be copied
      dest - Destination offset
      src - Source offset
      len - Length
