You'd have to confirm what encoding the server script expects, but  
posting files is normally done using a content type of multipart/form- 
data. (If you have an html version of the form, check if the form tag  
has an ENCTYPE attribute of "multipart/form-data".)

Then take a look at the libUrlMultipartFormData function. (I just  
noticed that the standard Rev dictionary leaves out an important  
piece of data in this entry. I think the docs incorrectly interpret  
some of the text as an xml tag.) I suggest you look at the web  
version of the libUrl documentation:
