Dear all,

I came across a caching problem while developing open social applications. I included a .js file like this in my widget xml file: <script src="host/bogusWidget.js"></script>

Every time I changed some code on bogusWidget.js file, the change wasn't immediatly reflected so I needed to wait for the cached request to clear.

This is the workaround I build for this, maybe it can help others with the same problem.

Here's a complete widget definition including a bogusWidget,js file that never gets cached:

<?xml version="1.0" encoding="UTF-8"?> <Module> <ModulePrefs title="Bogus Widget"> <Require feature="opensocial-0.7"/> </ModulePrefs> <Content type="html"> <![CDATA[

<script>

function include_dom(script_filename) { var html_doc = document.getElementsByTagName('head').item(0); var js = document.createElement('script'); js.setAttribute('language', 'javascript'); js.setAttribute('type', 'text/javascript'); js.setAttribute('src', script_filename); html_doc.appendChild(js); return false; };

function includeScript(url) { var refreshInterval=0; var ts = new Date().getTime(); var sep = "?"; if (refreshInterval && refreshInterval > 0) { ts = Math.floor(ts / (refreshInterval * 1000)); } if (url.indexOf("?") > -1) { sep = "&"; } url = [ url, sep, "nocache=", ts ].join("");

include_dom(url); }

includeScript("host/bogusWidget.js"); //Use this function instead of <script src="host/bogusWidget.js">

</script> <script> gadgets.util.registerOnLoadHandler(init); //Calling init method defined somewhere in bogusWidget.js file </script> ]]> </Content> </Module>

I hope this helps, its a solution mixing some DOM manipulation and the caching workround found in the API documentation for gadgets.io.makeRequest() return values.
