mbuni coding

I am receiving mms with Mbuni. I am making Mbuni process the mms and forward them to an URL via HTTP post. But currently Mbuni is coded only to forward or display a link which can be used to download or retrieve the MMS content. This is not what I want from Mbuni. I want to make mbuni display the mms content directly when posting to URL with HTTP post. This job is a coding job of Mbuni so that I can forward the content of the mms to the URL when I use Mbuni to post via HTTP Post to my website.
