echo_subrequest adds http headers

When changing:

echo_foreach_split ',' $filelist;
echo_subrequest_async GET '/getFile' -q 'file=$echo_it' ;
echo_end;

to

echo_foreach_split ',' $filelist;
echo_subrequest GET '/getFile' -q 'file=$echo_it' ;
echo_end;

the body is modified, and I see some http headers added:

@HTTP/1.1 200 OK^M
Server: ngx_openresty^M
Date: Wed, 02 May 2012 10:25:06 GMT^M
Content-Type: text/plain^M
Transfer-Encoding: chunked^M
Connection: close^M

Yes, the chunked encoding is enforced when subrequests are used this way. Because ngx_echo cannot know the total response body size beforehand. Also, you should adjust the Content-Type and other headers accordingly because subrequests' response headers will not be forwarded to the parent request.

BTW, please do not report issues regarding the ngx_openresty project (https://github.com/agentzh/ngx_openresty ) to the old Perl implementation of the OpenResty server. Report to the ngx_openresty github project instead. Thank you!
