bound URIs have no access to PUT request data about mongoose HOT 4 CLOSED

Hmm. Accessing PUT data, that sounds odd to me.
Could you elaborate more on your use case, please?
How do you setup a handler (do you know the name of PUT-ted files beforehand or 
do
you use wildcard), and why do you need to handle PUT request in the first place?

I am implementing a REST interface in an embedded application.  The put data 
needs to
be interpreted as an action to be executed inside of the embedded app. 

See http://en.wikipedia.org/wiki/Representational_State_Transfer for more on 
REST.

You can process PUT totally in embedded mode - just catch MG_NEW_REQUEST event,
and do mg_read().

Are you saying something like this?

myEventHandler(...)
{
...
if( !strcmp(ri->request_method, "PUT") )
   mg_read(conn, buf, 1024);
...
}

This does not work as the code inside mg_read skips everything for non-POST 
request. So it PUT doesn't work for PUT.

  if (strcmp(conn->request_info.request_method, "POST") == 0 &&
      conn->consumed_content < conn->content_len) {
