Hi

This is a off-topic for this group, but I've been unable to find a more
appropriate forum to ask this.

When I issue a POST request and include queryStrings... what if I also
have content?  What's the content look like?
For example, if I'm uploading binary data to a server, how would a
querystring (text) be included in the same content?  What confuses me
is it seems I'd be sending binary and text content.  How do I know
where to break up the message?

Another example would be a webserver providing access to the query
strings via the ServletRequest object.  But I can also get the input
stream.  So how would the server determine where the end of the
querystring content is vs the rest of the content.  Hopefully, this
question makes sense to you all.

Thank you,

John
