[Resolved] page not refreshing anymore

[chucklarge]

Hi,
On one of my sites, i have a navbar that shows the last 5 pages viewed generated with php. So from my main page, if i click on 'link 1' then go back to the main page, 'link 1' shows up in the last 5 pages viewed.

Ok thats fine and it used to work fine, but I just realised that it is no longer updating the last 5 pages viewed section until i manually refresh the page.
I am not sure, but think that this is related to some setting i changed in php.ini or httpd.conf . The setting i changed allowed the entries in a SUBMITTED html form to be cached? when i hit back.

I have been searching for what i changed and can not figure it out. Does anyone have any idea what this was?

you changed something but you dont have any idea what you changed?

ill take a guess here.... did you start sending this header?

Cache-control: private

I know i should remember, but I changed it a while back and it just dawned on me that that might be causing this problem. anyway, I am not sending that header.

I think this was something i changed in httpd.conf, so I am gonna post in an apache group. Thanks.

well I haven't been able to figure out what i changed, but I did find a solution to my pages cacheing.
These must be the first statements in your php code.

header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);

I put these on the pages that had the problem and they update correctly just as they once did.
