Read a HTTP Post request with some data

hi all,
I am using an Zencoder API to transcode video files. Once  the job is completed they will do a HTTP POST with XML or JSON data containing the Job ID and other info to the url we provide.


So if URL is www.abc.com/GetZencoderResponse.aspx or .ashx, how can I read the data they post?





excuse me for the underlines, i thought that would make my query stand out


Thanks in advance
