no-cache to force reload new page

[tshad]

I am having a problem with a page that loads a user control that absolutely
must reload if there are errors on the page.

But if you have IE set to never check for newer versions of the page, it
won't reload a new page. I have a random number being redisplayed on the
screen that doesn't get updated if the user has this setting set.

I tried the following on the page:

<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Expires" content="-1">

But that doesn't seem to work.

Is there a better way to do this?

Thanks,

Tom
