<body class='hmmessage'>I'm developing an app utilizing Comet quite extensively (coupled with Ajax).<br><br>I have gotten what I want to work and all at a basic level, but I do have a couple questions since I'm not at all familiar with the technology.<br><br>The first is, how do the pushers work? I tried throwing references to one around to just one, but I think it actually needs to be rendered to the page (load script) as per the example.<br><br>And the last one for now ;) is how can I restrict relevent data to the sessions that "care" about it? If a client pushes some javascript, but only a few other clients need that javascript, I would prefer to only give that script to those clients, or am I thinking on the wrong lines here?<br>Should I do something more along the lines of the CTCounter example where, when something in the data structure changes, then the clients can choose to do something about it?<br><br>Thanks!<br>RS<br><br><hr>From: dtrussardi@tiscali.it<br>Date: Sat, 20 Mar 2010 12:48:53 +0100<br>To: seaside@lists.squeakfoundation.org<br>CC: dario.trussardi@tiscali.it<br>Subject: [Seaside] Re: SUComponent script: question<br><br>
