you need to be more specific.

HTTP 2.x has a filtering schema which applies -protocol- filters
after all -content-.  Modules are presumed to generate content
unless they manipulate the filter stack.

mod_proxy dechunks the backend response (it's entirely possible
for httpd to accept chunking, and the proxy client to not accept
it as HTTP/1.0), since T-E is a hop-by-hop header.

So whatever *app server* you have that is chunking and not being
dechunked is an issue with the module you have receiving the
chunk response in httpd.  Chunking is not part of the CGI spec,
therefore it's invalid input to mod_cgi[d].  It's completely
legitimate for mod_proxy_http.  Tomcat has no such issues that
I'm aware of.

So what app server are you talking about?
