I was looking at 
and noticed that there was a section on "Refresh" that was not yet written.

My concern with "Refresh" is that I do not want it to be a global 
concept (a browser can only keep track of one refresh)--it looks to be 
implemented this way in Netscape 2.x.  I would like "Refresh" to apply 
to individual objects (RE: the message below to netscape).

This would allow individual GIF's within a document to be refreshed.

Help!  I have a great use for client-pull, but it is not working.

I have an html document with 10+ GIF images.  In the HTTP response 
header for each GIF (not the text html), there is "Refresh: 5".  You 
can see what I wanted to do!--I wanted NetScape to update each GIF 
within the document every 5 seconds, but it does not work.  Instead, 
what I see is that 5 seconds later, I see my document replaced by only 
one of the 10 GIFs.

Why is "Refresh" implemented as a global concept in NetScape? [It seems 
to launch a new document].

Why not instead assign "Refresh" TO AN OBJECT (NOT GLOBAL).  If the 
object to be refreshed is an html document, refresh the document.  If 
the object to be refreshed is an object WITHIN a document, update the 
object WITHIN the document (and do it smoothly, no flicker).

I could use server-push, but this requires extra coding.  Also, there 
is a potential for a new socket connection for each image, which I want 
to avoid (since I could have a LOT of images within one document).

I would really like to see this implemented.  If there is anything that 
I can do to help, please let me know.

Please respond and let me know what you think and does this have any 
chance of being implemented.  Thanks.
