| Re: [jetty-users] ServletResponse with ProxyServlet.Transparent is empty |
String receivedContent = new String(buffer);
LOG.info(">>> conent: " + receivedContent);
// <modify string here>
super.onResponseContent(request, response, proxyResponse, buffer, offset, length);
I didn't modified the content yet. I only printed out the content, but then the program halts at this point. Do you have any Idea how i can modify the content at this point?
kind regards
Hi,
ProxyServlet is asynchronous. Your filter calls filterChain.doFilter()

which hits the ProxyServlet which proxies the request and returns
immediately without blocking waiting for the response.
On the next line of your filter you expect the content to be arrived,
but it's not arrived yet, because the whole processing is
asynchronous.
If you want to modify the content the proxy sends to the client,
override ProxyServlet.onResponseContent().
