How can I force explorer to reload Flex page( swf embedded in HTML)?

Question

Hi guys,

I developed a flex website, the web explorer always caches swf file which embedded in HTML. Sometimes I make changes to the flex file, clients computer still view the previous version which stored in cache. How can I force client's web explorer to reload/refresh the swf file?

Thanks

Answer 1

You can add a version number to the URL of the swf file, kind of like this:

<object ...
   <param name="movie" value="my.swf?version=2" />
   ...
   <embed src="my.swf?version=2" ...
</object>

When you have a new changed swf file, you also change the version number in the URL, so the next time it will be my.swf?version=3 and so on.

It doesn't need to be a version number, the idea is simply that since the URL to the swf is new, the browser wont use a cached file.

Three (different) ways:

1) Try the no-cache tags

2) Use a preloader, which is a flash movie that loads the swf

3) Add the swf to the page with javascript and add a random url variable to the end to make it a different name every time, and therefore forces the browser to reload it

Answer 3

I would use jQuery and simply delete it then put it back.

I use that on my pages and it works very well
