I searched in the forum and did not find a definitive solution, my problem is with regard to browser cache, when I make a change in a javascript file, my client only gets the updated file after cleaning the cache.
We have treated as code below:
<script src='<%=Page.ResolveClientUrl("~/Scripts/MeuJavaScript.js?sid=" + Session.SessionID) %>
Where we concatenate the user session to the file link, however, even with this the file remains outdated.
Thank you.

You can configure the browser through the meta tag not to cache the content of your site, this way:
<meta http-equiv="cache-control" content="max-age=0" />
<meta http-equiv="cache-control" content="no-cache" />
<meta http-equiv="expires" content="0" />
<meta http-equiv="expires" content="Tue, 01 Jan 1980 1:00:00 GMT" />
<meta http-equiv="pragma" content="no-cache" />
Update
You can make at the beginning of your script an ajax request to check the version on your server, so every time it updates you run the command:
window.location.reload(true)
Or send a message to the user informing about the new script.

Have you tried using instead of Session.Sessionid, force some other concatenation just to see if it updates? I don’t know, just put a random number in front and see if you catch up.
