boolean handleRequest(javax.servlet.http.HttpServletRequest request,
                      javax.servlet.http.HttpServletResponse response,
                      javax.servlet.ServletContext servletContext)
               throws javax.servlet.ServletException,
                      java.io.IOException
```
    This method handles the HTTP request. If the plug-in decides to handle the request, it will populate the HTTP response object with the information needed to return the result. It will then indicate that the request was handled thus should not be passed along for further processing. If the plug-in does not handle the request then the response object cannot be modified. This method will only throw exceptions related to generating the response to the request. Exceptions occuring during processing whether the plug-in should handle the request should be caught and false should be returned.
    
    Parameters:
    
    request - The HTTP request object.
    
    response - The HTTP response object.
    
    servletContext - The servlet context of the servlet calling the plug-in.
    
    Returns:
    
    Returns whether the preview request handler handled the request. A value of true means that the plug-in has handled the request and produced a response. A value of false means to either use another plug-in to handle the request or forward the request to the stores web application for processing.
    
    Throws:
    
    javax.servlet.ServletException - A problem occurred when modifying the response object.
    
    java.io.IOException - A problem occurred while writing the response in the response object.
