Yes it looks like a cgi script or some active content wrongly generated.
It is now fixed, the parser is by default in "lenient" mode, as it should

1.0 requests are translated to 1.1 requests by the proxy, so it is valid
for the server to send chunked streams, however, the stream detection was
not right, and in that case the content length was the first thing
checked. Now it is done the right way and you can see all the pictures.
