Thank you Julius for explaining why this does not work on websockets and for the suggestion about the WriteStream method.  I did use Nicholai's sample method to implement the changes to work around this issue.  Much appreciated.

Thank you Nicholai for this method.  I made a few modifications to the code but I very much appreciate the great starting point.

Thanks Dmitry.  This worked perfectly and fixed an issue we had with a vendor that wanted empty fields removed from messages sent to them.  Much appreciated.
