I see the odd error log entry where a user is getting a wrong version number. I know this is due to their browser caching an older version. Is there a way to force the browser to update their version? I can’t exactly start contacting the customers effected and tell them to refresh their browser cache or do a shift-f5, that doesn’t scale.
That being said I have a suggestion for the fine folks at Vaadin. What if the JS bootstrap file was renamed to include the Vaadin version, or something like that which would require a browser refresh? I know the browser is suppose to do some checks but it doesn’t always work, the only sure fire way I read to resolve it is to rename the file. To be honest even a build timestamp would probably be better because it would force updates if there were changes within the same version.
Are you using something older than that?
