The inets HTTP-Client API states that a request could be:

request() - {url(), headers()} |
      {url(), headers(), content_type(), body()}

where body is:

body() = string() | binary() 

So in your case that would be:

Bleh = #Record{define="stuff"},
http:request(post,{"http://blehbleh", [] ,
	    "text/plain", term_to_binary(Bleh)}, [] , []).
                                              ^^^ 
                                              note not "." but ","

As noted above: On the client side the post body should be of type
string() or binary().

How yaws works I will leave to Clacke to explain ;)
