public HttpEngineEnvironment(HttpServletRequest _request,
                             Map<String,Object> _mRequestParameters,
                             HttpServletResponse _response)
```
    Creates a new instance of HttpEngineEnvironment.
    
    Parameters:
    
    _request - the servlet's request parameter
    
    _mRequestParameters - free typed request parameters
    
    _response - the servlet's response parameter
- Method Detail
  - isInstanceOf
```
public boolean isInstanceOf(String _sTypeName)
```
    Checks whether this class or an ancestor is an instance of the given type name.
    
    Specified by:
    
    isInstanceOf in interface EngineEnvironmentI
    
    Overrides:
    
    isInstanceOf in class ServletEngineEnvironment
    
    Returns:
    
    true if and only if the given type name equals "HttpEngineEnvironment" or one of the type names of the ancestor classes.

  - getCookieValue
```
public String getCookieValue(String _sName,
                             String _sDefault)
```
    Returns the value of the cookie (sent along with the request) with the given name. If no such cookie exists then the given default value is returned.
    This is a convenience method for accessing a cookie's value. In order to access all cookie data, an array containing all Cookie objects can be obtained by calling getCookies().
    
    Parameters:
    
    _sName - name of the requested cookie
    
    _sDefault - default return value (default = null)
    
    Returns:
    
    the value of the cookie with the given name if such cookie exists, otherwise the given default value

```
public Cookie[] getCookies()
```
    Returns an array containing all the Cookie objects the client sent with the request. If no cookies where sent the returned array is empty.

  - createCookie
```
public Cookie createCookie(String _sName,
                           String _sValue)
```
    Constructs a Cookie object for a specified name and value, to be used later as the parameter to method setCookie(Cookie).
    Note: This method only creates a Cookie object but does not set the cookie in the engine environment.
    This is a factory method wrapped around the Cookie(java.lang.String, java.lang.String) constructor.
    
    Parameters:
    
    _sName - the cookie's name. See Cookie(java.lang.String, java.lang.String) on restrictions of the characters allowed for cookie names.
    
    _sValue - the cookie's value See Cookie.setValue(java.lang.String) on on restrictions of the characters allowed for cookie values.
    
    Returns:
    
    a newly allocated Cookie object with the given name and value

                      String _sValue,
                      int _iMaxAge)
```
    Sets a cookie with the given name, value, and maximum age. If a cookie with the given name already existed it is overwritten. The cookie data will be sent along the servlet reply to the client.
    This is a convenience method for setting a cookie's value. In order to set other attributes of a cookie it should be set by calling setCookie(Cookie).
    
    Parameters:
    
    _sName - the cookie's name. See Cookie(java.lang.String, java.lang.String) on restrictions of the characters allowed for cookie names.
    
    _sValue - the cookie's value See Cookie.setValue(java.lang.String) on on restrictions of the characters allowed for cookie values.
