String com.quadcap.http.server22.HttpResponse.encodeRedirectUrl ( String url )

Encodes the specified URL for use in the sendRedirect method or, if encoding is not needed, returns the URL unchanged.
The implementation of this method should include the logic to determine whether the session ID needs to be encoded in the URL. Because the rules for making this determination differ from those used to decide whether to encode a normal link, this method is seperate from the encodeUrl method.
All URLs sent to the HttpServletResponse.sendRedirect method should be run through this method. Otherwise, URL rewriting canont be used with browsers which do not support cookies.

Parameters:

url the url to be encoded.

Returns:
the encoded URL if encoding is needed; the unchanged URL otherwise.

String com.quadcap.http.server22.HttpResponse.encodeUrl ( String url )

Encodes the specified URL by including the session ID in it, or, if encoding is not needed, returns the URL unchanged.
The implementation of this method should include the logic to determine whether the session ID needs to be encoded in the URL. For example, if the browser supports cookies, or session tracking is turned off, URL encoding is unnecessary.
All URLs emitted by a Servlet should be run through this method. Otherwise, URL rewriting cannot be used with browsers which do not support cookies.

Parameters:

url the url to be encoded.

Returns:
the encoded URL if encoding is needed; the unchanged URL otherwise.

Parameters:

sc the status code

msg the detail message

Exceptions:
