Migrate from IIS to QVWS

BuTbka — Mon, 26 Jan 2026 18:19:17 GMT

We are want to move from IIS to QVWS, because there are a lot of problems with IIS.

We tried to do this in our test environment. After migrate users cant see AP before they clear cache and cookies.

We have 3000 users and we cannot to clear they caches. Is there any solution?

@BuTbka because QlikView is an In memory software there isn't a way around this. Your users will just need to clear their browser cache and cookies to resolve this. Unfortunately, there isn't any known workaround for this.

Thanks for reply. But I think there is no link between the in-memory software and browser cache or cookies.
I think that maybe some workaround fo QVWS like for IIS in this article https://support.qlik.com/articles/000097401

Hi @BuTbka,

You can add custom HTTP Response Headers to the %ProgramData%\QlikTech\WebServer\config.xml file, so your request may be possible. Refer to the Qlik Support article QlikView WebServer: Custom HTTP Header for more details.

Best Regards
