Summary  |  Top

   public PageWrapper() 

Default constructor

   protected InputStream getPageStream(HttpServletRequest req, 
                                       HttpServletResponse res)  throws IOException

Munge the URL for the requested page to generate the primary content.

Overrides:

getPageStream in class BasicWrapper

   protected URL unwrapURL(HttpServletRequest req)  throws MalformedURLException

Given a request, strip out the /servlet prefix and return a stripped URL.

        Example: If a client requests:
            http://www.interstice.com/servlet/PageWrapper/~kevinh/index.html
        This routine will return:
            http://www.interstice.com/~kevinh/index.html
        

   protected InputStream urlToStream(HttpServletRequest req)  throws IOException

Convert an HTTP request into an appropriate base input stream. This involves stripping off the /servlet prefix and then generating a new URL. We then open the URL and return the result.

        Example: If a client requests:
            http://www.interstice.com/servlet/PageWrapper/~kevinh/index.html
        This routine will return the contents of:
            http://www.interstice.com/~kevinh/index.html
