Stylesheet load/cache issue

Question

I have made a change to my css file and deployed to an IIS8 server on Windows 2012 R2. I am linking from an ASPX page.

If I have ...

<LINK href="./GolfBookings.css" type="text/css" rel="stylesheet">

The old version of css will be served.

If I have ...

<LINK href="./GolfBookings.css?43784378" type="text/css" rel="stylesheet">

The correct version is loaded. Great, but if I go back to ...

<LINK href="./GolfBookings.css" type="text/css" rel="stylesheet">

the old version will be served again. This behavior persists across application pool recycles and even a windows server reboot. 

Ideally, I would like the new stylesheet served without any change to the aspx file including dodgy query strings.

Thank you

Hi,

It seems you're developing a asp.net website, the easiest solution would be append a version to your CSS file when you updating your CSS.

Here are two threads for your reference.

If you're using SharePoint, you could check below thread for solutions.
