Disable caching on a partial view in MVC 3

I have an issue with a partial View being cached when it shouldn't be. This partial View is used to display the Logon/Logoff on a page. It uses the simple code below to figure out which link to display 

@if(Request.IsAuthenticated) {    
    <a href="@Url.Action("LogOff", "Account", new { area = "" })">Log Off</a> 
}
else {
    <a href="@Url.Action("LogOn", "Account", new { area = "" })">Log On</a>
}

This partial View is called from with all pages in my MVC3 application, using 

@Html.Partial("_HeaderView")

In most of my controllers, I have the output cache defined, so I can take advantage of caching my content. 

[OutputCache(Duration = 86400, VaryByParam = "*")]

Now my issue is that the entire page is being cached when I don't want the partial view to be. This is causing wrong behavior where in it sometimes displays LogOff even if the user is not logged in etc. Is there a way to cache all the content, except for the partial view in question?
