Hi,

I don't have enough data to understand exactly where your problem come
from. Your use case is pretty simple and should work fine. Can you
provide us with the yaws scripts you use to be sure ?

You could also enable traces in Yaws to dump content of the requests and
the responses. It is a simple way to see inputs/outputs from Yaws point
of view.
The trace files will be written in your logdir, in a subdirectory
trace_<YYYYMMDD_hhmmss>. To enable trace, you should set the parameter
"trace" to http or traffic in your yaws.conf file. See
http://yaws.hyber.org/yman.yaws?page=yaws.conf for details.
