When displaying data from DB usually I'm in this situation
I'm in page A.php that shows data from DB,
user performs some action (like edit/delete etc) and page B.php is loaded to perform the action,
once page B performed the action, it redirects browser to page A,
page A is auto reloaded during step (3) therefor it shows an updated situation of the data
In order to make page B to redirect to page A i use a simple PHP
header("Location: " . "A.php", TRUE, 302);
This works well in all situations, except when pages A.php is displaied into an <iframe>: in such a case it does not reload (step 4 does not get done).
This seems to happen only in IE7 (don't know about IE8), it works perfectly on FF/Safari.
And only when using an <iframe>, if page A.php is not in <iframe> it gest refreshed also in IE7.
In order to solve this I simply added a couple of headers in page A.php to set it to not be cached:
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
But I was curious if you migt have exeperienced the same issue too in the past, and if you good give me some advises about this.
Thanks!
