thanks for your answer! You are right, that works!
Buy how exactly can I modify the content at this point? I tried this little
example:
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
