*
|
|
* An example of the stream that may return non-0 from this function is
|
|
* an HTTP stream with the value returned taken from the "Content-Type"
|
|
* HTTP header. Note also that if the encoding of the data is known
|
|
* to the application by some other means then the setEncoding function
|
|
* in the InputSource object should be used instead. The getContentType
|
|
* function should only be used to return information that is intrinsic

* to the stream.
