Difference between httpservlet and dynamoservlet

  

HttpServletRequest/Response	DynamoHttpServletRequest/Response
The HttpServletRequest/Response interface is immutable	DynamoHttpServletRequest/Response interface is mutable
HttpServletRequest only  provides methods for reading the various properties, but does not provide methods for setting those properties	DynamoHttpServletRequest, which implements HttpServletRequest provides methods to change request properties, such as setPathInfo, setPathTranslated etc.
HttpServletResponse only  provides methods for reading the various properties, but does not provide methods for setting those properties	DynamoHttpServletResponse, which implements HttpServletResponse, lets you change response properties such as the output stream, and access its values such as statusCode etc.
HttpServletRequest and Response object are directly passed  as an argument to the servlet's service methods (doGet, doPost, etc)	The very first element of the servlet pipeline converts an incoming HttpServletRequest/Response pair into a DynamoHttpServletRequest/Response pair. This allows subsequent elements of the servlet pipeline to use the additional functions provided by DynamoHttpServletRequest/Response.
