Constructor Detail

CoyoteAdapter

public CoyoteAdapter(Connector connector)

Construct a new CoyoteProcessor associated with the specified connector.

Parameters:

connector - CoyoteConnector that owns this processor

Method Detail

event

public boolean event(Request req,
            Response res,
            SocketStatus status)

Event method.

Specified by:

event in interface Adapter

Returns:

false to indicate an error, expected or not

service

public void service(Request req,
           Response res)
             throws java.lang.Exception

Service method.

Specified by:

service in interface Adapter

Throws:

java.lang.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 )

log

public void log(Request req,
       Response res,
       long time)

Specified by:

log in interface Adapter

postParseRequest

protected boolean postParseRequest(Request req,
                       Request request,
                       Response res,
                       Response response)
                            throws java.lang.Exception

Parse additional request parameters.

Throws:

java.lang.Exception

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 -

request -

parseSessionId

@Deprecated
protected void parseSessionId(Request req,
                             Request request)

Deprecated. Not used since 6.0.33

Parse session id in URL.

parseSessionCookiesId

protected void parseSessionCookiesId(Request req,
                         Request request)

Parse session id in URL.

convertURI

protected void convertURI(MessageBytes uri,
              Request request)
                   throws java.lang.Exception

Character conversion of the URI.

Throws:

java.lang.Exception

convertMB

protected void convertMB(MessageBytes mb)

Character conversion of the a US-ASCII MessageBytes.

normalize

public static boolean normalize(MessageBytes uriMB)

Normalize URI.

This method normalizes "\", "//", "/./" and "/../". This method will return false when trying to go above the root, or if the URI contains a null byte.

Parameters:

uriMB - URI to be normalized

checkNormalize

public static boolean checkNormalize(MessageBytes uriMB)

Check that the URI is normalized following character decoding.

This method checks for "\", 0, "//", "/./" and "/../". This method will return false if sequences that are supposed to be normalized are still present in the URI.

Parameters:

uriMB - URI to be checked (should be chars)

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.
