What is the different between "GET" and "POST" ?

If, using "getInputStream()" to get an "Inputstream" to retrieve data that be sent with "POST" format, then...
(1) How to get each item value ? Refer to following example please:
<FORM METHOD="POST" ACTION="test">
<INPUT TYPE=TEXT NAME="TXT1">
<INPUT TYPE=TEXT NAME="TXT2">
....
</FORM>

  All thoses items("TXT1","TXT2"...) and their values are read from "input stream", but, how to  get their value ? Read and check everyone ?

(2) What does mean "read binary data from the input stream. " ? It can also be done with "getParameter()" , right ?

ITman,

I do not think that it would make a lot of sense to use getInputStream() to access items from an html form, but you could.  You would have to parse the stream yourself and there is little point to do that since it is already done for you if you use request.getParamter(...).

The HTTP POST is not limited to the content type under which html form data is sent.  If you are sending other kinds of content, then it may be necessary to provide your own logic to process the data sent in the POST request.

Cheers,
Ken Jones
