nocache but still allow back button

[c_note]

Having trouble with this -- can't seem to find a difinitive answer.

I have a page that displays a new image from a post. But when I return to this page by clicking the back button, the page has expired.

Does anyone know how to disable cache BUT STILL still allow the user to click the back button (in the browser) and have a dynamic page displayed (ie data is drawn from the database).

Two problems: 1) If I disable the cache I can obtain the non-cached page by clicking a link that returns to this page. 2)If I enable cache, I get a cached page but I can click the back button. Catch 22 situation. Any way around this???

*note:

- I have tried header, session_cache_limiter, etc, etc.
-I do NOT want to use get instead of post

Thanks so much.

Mike.

Put the enitre page in a print(); function.

<?
print ("
blah blah
");
?>

PHP will read the page from scratch. If you are presenting a single image dynamically for that specific page, make a cookie called 'last' and use:

<?
print ("
blah
<img src=".$last."
blah
");
?>

Not quite sure what you mean. This is the page that has problems:

http://66.216.80.41/pup/pup.php

To reproduce the error: Click on one of the radio buttons 'Make Main', then click the 'Update Main' on the left, then click the back button in your browser.

Thanks.
