Thanks so much for your help! This will help me out a lot!

Yup, this should do it.

<?php
/* create timestamp in the future */
$future = strtotime('+7 Days');

/* format it to be sent to the header */
$future_formatted = date('D, d M Y H:i:s T', $future);

/* send cache header */
header(\"Expires: ' . $future_formatted . '\");
?>

Is it possible to make a date variable for the header and then set the cache to expire in, say, 24 hours? I don't want to keep updating the expiration date/time.

I think this is because their browser isn't caching the page, and it's being reloaded every time. Here are a couple of ways you can fix this.

1) Set the cache time of the page (assuming PHP). Set the 'expires' date to some point in the future.

<?php
header(\"Expires: Mon, 26 Jul 1997 05:00:00 GMT\");
?>

2) Instead of having the site visitors use their back buttons, provide a link where they can go back like "< Back to List of Items". Then, use an anchor tag to make that link go to the correct spot in the page. The back link should point to a location like http://www.example.com/items.php#item12345

I have index (master) pages that list items and breif descriptions of them. Those links go to details pages for the items, where all of the details of that item are listed. When you go from the index page to the details page, and press the back button in the browser, the items are queried and listed again, from the very first item. Therefore, if the user goes from the index to the details page and uses the back button in the browser, the user has to look over the list of items again and find where they were before, by scrolling down the page. I don't want them to have to scroll back to where they were.

In contrast, I've noticed that static pages do what I want them to do, that is, go right back to the place on the index where the user last viewed.

Does that make more sense?

Could you please explain a bit more about what it is you want to achieve? I don't completely follow you...
