[bug] possible bug in output chains

[Manlio Perillo]

Hi.

When doing some tests with mod_wsgi I have found a possible problem with 
nginx output chains.

I write two separate buffers, of size <~ 1024 bytes, and a final 
ngx_http_send_special(NGX_HTTP_LAST).

The problem is that nginx sends to the client the content of the last 
buffer only, two times.

If the buffer is large enough, or if gzip filter is enable, the output 
is correct.

I don't know if this is a bug in mod_wsgi.



Thanks  Manlio Perillo
