Hello,

Is output caching supposed to serve page refreshes from the cache or is the
page re-run?

I have a very simple test page that does send the cached response if I
retype the url in the browser or if I access the page from a second browser
window.
If I open the page, and then hit the refresh button on my browser, then the
page is re-run every time I hit the refresh button, and I do not get the
cached version.
Is there something I am missing (web.config maybe?...I do not see anything
in my web.config file about caching) that is causing this behavior or is
this normal.
I have also tried wrapping the CreatedStamp.InnerHtml = Now() line in an If
Page.IsPostBack = False block, but this also did not change the behavior
described above.

I am running Windows 2000 Professional, and the .Net framework that came
with Visual Studio .Net Beta 2.
The code for my page (SimpleExample.aspx) is below:

<%@ OutputCache Duration="60" VaryByParam="none"%>

<Script runat="server">
Public Sub Page_Load()
CreatedStamp.InnerHtml = Now()
End Sub
</Script>

Output Cache created: <label id="CreatedStamp" runat="server" />

As always, thank you for your assistance,

Tom Skowronski

Have you installed the Premium version of ASP.NET, available at www.asp.net?
With Beta 2, that was required to get caching and a couple of other
features.

hi thomas
i copied your code into a new file, and the caching worked properly. showed
the cached version with the same creation date, until i waited more than 60
seconds, then it made a new version. same effect across new sessions /
browser windows.

i don't have any caching settings in web.config file.

no ideas why it shouldn't be working.
anyone else?

I can't reproduce this...

What browser are you using?

Thanks
