During the zero-copy data forwarding, the caller specify the maximum amount of data the producer may push. However, the HTML stats applet does not use it and can fill all the free space in the buffer. It is especially an issue when the consumer is limited by a flow control, like the H2. Because we may emit too large DATA frame in this case. It is especially visible with big buffer (for instance 32k). In the early age or zero-copy data forwarding, the caller was responsible to pass a properly resized buffer. And during the different refactoring steps, this has changed but the HTML stats applet was not updated accordingly. To fix the bug, the buffer used to dump the HTML page is resized to be sure not too much data are dumped. This patch should solve the issue #2757. It must be backported to 3.0.
