Subject: Re: How to *not* return a page
Mime-Version: 1.0
Content-Type: text/plain; charset=US-ASCII

By "may or may not", I mean that the Javascript
does necessarily continue on and request a page;
in other words, I am sending a request to the=20
server to set a session value and the web page
itself is "not interested" in the response and does
not want to be changed in any way by the response.

I am not sure what you mean by "that doesn't  have=20
to happen directly within the flowscript function called by the=20
sitemap, in just has to eventually happen in the call chain."
If a sendPage is not the only way to end a flowscript
function, then what are other ways?  And why does the
"call chain" have to send a page back to the browser
ie. where is the option for "one way" communication
from client to server?

Thanks
Derek

Can you clarify the "may or may not" part there? In particular, what=20
does "may not" look like? The client has issued a request, and there=20
must be a response. So if Cocoon doesn't generate that response, where=20
does it come from?

One way or another, yes. But of course that doesn't necessarily have=20
to happen directly within the flowscript function called by the=20
sitemap, in just has to eventually happen in the call chain.
