Re: [Flashcoders] Flash Cache in IE FF
You can append a query string to any URL and this forces a reload of the data from the CLIENT. For example, as someone has already pointed out. Main.swf?nocache=+(new Date()).getTime() You can also do this to your data file. myData.xml?nocache=+(new Date()).getTime() As you might have noticed, I was specific about this working to force reloading on the client. It has been my experience that this is not a 100% solution. There are some instances where the server will cache the data and query strings do not force the reloading of data. The server cache would eventually update after a few hours though. To be honest I do not know the solution to this part of the puzzle. I put that issue on the laps of the server administrator. I know that it took his several patches to fix the issue for users off domain. I do recall that people on the same domain were still getting caching issues. This was finally chalked up to a FOL (fact of life). To provide full disclosure, this was a fairly complex network and domain config. as it was for a major financial institution. So, the problem might have been self induced and thus unique to the company. Charles P.

RE: [Flashcoders] Flash Cache in IE FF
Hi Don, The conventional way to avoid loading cached content into Flash is to call a unique URL for the content every time. One way to do this is to append a random number or UTC timecode (in milliseconds) to your URL, for example (AS3): var l:Loader = new Loader(); var req:URLRequest = new URLRequest(your url here); var vars:URLVariables = new URLVariables(); req.method = URLRequestMethod.POST; vars.antiCache = Math.round(Math.random()*99); req.data = vars; l.load(req); Hope that helps...
