Commented Unassigned: Combined scripts are not cached [27531]

Hello,
I just tried to set up combined scripts with the last version of ACT and it seems that scripts are never cached.

page.aspx
```
<act:ToolkitScriptManager runat="server" ID="ScriptManager1">
</act:ToolkitScriptManager>
```

AjaxControlToolkit.config
```
<ajaxControlToolkit>
<controlBundles>
<controlBundle>
<control name="ModalPopupExtender" />
</controlBundle>
</controlBundles>
</ajaxControlToolkit>
```
web.config - handlers added

See attached screen. Everytime page is reloaded, all scripts are loaded from cache, except ACT.
Any solution for this?
Comments: I had the same problem. It could be an Internet explorer issue because the cache does work for Chrome. It does not work with Internet explorer 11. I confirmed it also in the IIS LOGs.
