Yes, http allows custom headers and different values
in headers and custom tags (they just aren't displayed
by browsers...or should not be...though in this case
you are using HttpClient).  The issue is whether or
not you have a server and/or a client to support your
custom headers and values.  Basically you could make
this work as defined in this document on your own. 
You will need to parse the headers and the document
yourself and perform actions based on those values. 
Though you should read more for your own sake and
sanity...

>From the document:
"The key to the use of this technique is that the
server does not push the whole
"multipart/x-mixed-replace" message down all at once
but rather sends down each successive data block
whenever it sees fit. The HTTP connection stays open
all the time, and the server pushes down new data
blocks as rapidly or as infrequently as it wants, and
in between data blocks the browser simply sits and
waits for more data in the current window. The user
can even go off and do other things in other windows;
when the server has more data to send, it just pushes
another data block down the pipe, and the appropriate
window updates itself."

Translation of quote to issue:
You can't easily pool your HttpConnections when doing
something like this as the HTTP connection is held
open the entire time.  If you expect many
users....ouch...you'll run out of connections.  You
are better off creating a check and update scenario so
you can better load balance your application.
