It does seem that Mod_JK does not handle correctly the case when Transfer-Encoding header is set to chunked on HTTP response returned from Tomcat via AJP. Transfer-Encoding is set on HttpServletResponse and no Content-Length header is set. In this scenario Mod_JK returns response to client with Transfer-Encoding set to chunked, but it fails to set chunk-size before the body. When the same response is returned with no Transfer-Encoding and no Content-Length set, Mod_JK correctly sets Transfer-Enncoding to chunked and sets the chunk size.
Now, Transfer-Encoding is a hop-to-hop header and does not have to be set on the response from Mod_JK to client, but when it is I would expect Mod_JK set the chunk size. This seems to me like a bug. Mod_Proxy has no such issue. Here's my setup: Server Apache/2.2.11 (Win32) mod_ssl/2.2.11 OpenSSL/0.9.8i mod_jk/1.2.27 Apache Tomcat 5.5.30 using AJP/1.3. Andre Piwoni
