I have a global js function that handles
this… always makes sure the parameter after the ? is new, therefore the
file is always loaded new on the client… …once you get your application to a
stable “release” point though, maybe think about going back to the
old way… because this could potentially fill up your users’
harddrives… // use these functions to include
references to extrenal files that might change frequently // (main use is for testing... it's
annoying to have to delete IE's temp files every time I make a change to a js
or css file) function IncludeScript(externalFile,
defer) { var deferStr = ""; if (defer) deferStr = 'defer="defer"'; document.write('<script
type="text/_javascript_" src="" Date() * 1+'"
' + deferStr + '><\/script>'); } From: In it's very simple form you can do this
- For first time include the js file like this - <script src=""
type="text/_javascript_"></script> After updates include it like this - <script src="" type="text/_javascript_"></script> Keep bumping up the version number. Now there are lots of better ways of doing this and creating
automated versioning by checking the md5 of the file etc etc, but this should
solve your problem. Thank you, From: Hi folks, So I’ve got this app built on prototype,
with a bunch of extra JS classes to do what we want. Now the problem is,
when I make a change to one of those JS files (or an upgrade to prototype
itself), how do I ensure that the client browsers refresh their cache with the
latest JS? Clearly I want the browse to cache the
large JS files, but I also want that cache to expire at some point, or I want
to be able to force a re-fetch of all the scripts/css referred to (the
equivalent of a shift-reload). This must be a solved problem, but I
didn’t see the solution anywhere… do I stick something in the http
header of the JS file?
