Hi, I know of three gotchas with RSH (none of them specific to Prototype):
1. You _have_ to call `window.dhtmlHistory.create` from a script tag in the `body` element of your page, because it uses `document.write` (sadly) to write elements during the course of that call. I have it right at the end of my `body` tag. 2. You _have_ to call `window.dhtmlHistory.initialize` from the window `load` event or later, not earlier (for instance, not from dom:loaded). 3. You _have_ to have a file called 'blank.html' alongside the HTML file you're using rsh.js in (or edit rsh.js to change the name and/or path of that file). YMMV, but looking at an app where I used it and it seems to work okay, I call this function from with the `body` tag: function writeHistoryElements() { window.dhtmlHistory.create({ toJSON: Object.toJSON, fromJSON: function(s) { return s.evalJSON(); } }); } ...and then this code one once `window.load` has fired: var history = window.dhtmlHistory; history.initialize(); history.addListener(historyChange); if (history.isFirstLoad()) { // Do anything you may want to do on the first load } Example: http://pastie.org/1103706 I don't use the data feature, just the notification of hash changes -- I store all state I'm going to need in the hash or on the server, so that all URLs are bookmarkable. I think the idea of the data stuff is that you can cache stuff on the client, but I don't need that for this app and the data stuff didn't seem to work very well cross-browser (RSH hasn't been maintained in a while).
