Hi, Content-length isn't required if chunked transfer encoding is used. Chunked transfer encoding let's you stream your output and won't know the length in advance to communicate with the caller.
Yes, I found this info just one minute after posting this thread. Now...I've got two solutions for displaying the progress bar:
- i change a setting in jboss for returning a unique response (not chunked) with a content-length field (so I can show the progress percentage in the progress bar). But: I don't know which setting and where it is;
- i find a way to display a usefull progress bar with chunked response. But: for now i don't have ideas
