I am trying to skip going through filter in my code if
certain condition
met(i.e. rss.xml or rss.rdf)
But after doing all kind of R&d i am unable to make it.
My tried code is mentioned below.
any modifications suggested.
if(totaluri.endsWith("rss.rdf") &&
auth_string==null){
in this line i am trying to make this but it always gpes to
if(auth_string==null){
where authecation is must.
My ultimate goal is to read rss.xml/rdf in rs reader which
is present
outside the program.
where i can't pass username and password stuff.
public void doFilter(ServletRequest request, ServletResponse
servletresponse, FilterChain chain)
throws IOException, ServletException {
// Create wrappers for the request and response
objects.
// Using these, you can extend the capabilities of
the
// request and response, for example, allow setting
parameters
// on the request before sending the request to the
rest of the
filter chain,
// or keep track of the cookies that are set on the
response.
//
// Caveat: some servers do not handle wrappers very
well for forward
or
// include requests.
