Re: Refreshing an SL4 app (client problem?)

If you use the last modified time of the xap file then you will download the new version and if its updated then you automatically get the new one, but don't download it every time (which would happen if the url was different on every page load.) you only want the client to download it if the xap file has changed. put the modified date/time in the url and forget about it. move on to more interesting problems. :) On Thu, Sep 8, 2011 at 12:12 PM, Greg Keogh g...@mira.net wrote: http://stackoverflow.com/questions/2281919/expiry-silverlight-xap-file-from-browser-cache-programmatically ** ** Interesting ... some solutions are browser specific, some need code and maintenance.

RE: Refreshing an SL4 app (client problem?)
I have used this approach too. I actually have a Build.txt in the root of the application, and set the build number in the web.config and I use: App.xap?v=2.0.0.1 The query string difference is also enough to invalidate the cache, and it can be put into the build process easily and only invalidates on a new build.

Hi Greg, Funny, I was dealing with this today We handle this by having a version number in the xap filename (eg. SLAppName1.5.2.xap). This way whenever a new build goes on production, we know browsers will referencing the correct one. Simon.

It's because the browser is caching the app, and your IIS probably doesn't set any cache expiry headers.

When browsing from my work machine I see the old version. So I restart my localhost IIS and delete temporary files in the browser, but it makes no difference. As an administrator I delete all local v2 and v4 ASP.NEThttp://ASP.NET temporary files and restart IIS, now it's fixed. So it looks like the problem was on my client side, not on the server machine side. I'm not sure which step fixed the problem, but it *might* have been deleting the local temporary files.
