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
  - asyncDispatch
```
public boolean asyncDispatch(Request req,
                    Response res,
                    SocketStatus status)
                      throws Exception
```
    Specified by:
    
    asyncDispatch in interface Adapter
    
    Throws:
    
    Exception
  - service
```
public void service(Request req,
           Response res)
             throws Exception
```
    Service method.
    Specified by:
    
    service in interface Adapter
    
    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 )
  - errorDispatch
```
public void errorDispatch(Request req,
                 Response res)
```
    Specified by:
    
    errorDispatch in interface Adapter
  - log
```
public void log(Request req,
       Response res,
       long time)
```
    Specified by:
    
    log in interface Adapter
  - 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 Exception
```
    Parse additional request parameters.
    
    Throws:
    
    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 -
  - 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.
  - parseSessionCookiesId
```
protected void parseSessionCookiesId(Request request)
```
    Parse session id in URL.
  - convertURI
```
protected void convertURI(MessageBytes uri,
              Request request)
                   throws Exception
```
    Character conversion of the URI.
    
    Throws:
    
    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.
