In general, open HTTP VBO and see how it works. (Or you can always create your own VBO)
Basically ""Post Data"" should contain one row, rest is ignored. Get Body stage builds a string from it, for each column in that row in it adds urlencoded ""ColumnName=Value"" pairs separated by &
Binary files are normally sent by browser as multipart/form-data instead of application/x-www-form-urlencoded, because latter adds significant overhead for big binary files - it looks like you'd have to create your own action for multipart/form-data, if you need it.
Nevertheless, server should be able to accept application/x-www-form-urlencoded file too, which can be sent with HTTP VBO... just be prepared that your request might end up like 2-3 times the size of the actual file.
