Hello

How to handle the message "pages has expired"

I'm working with frames.
1 top, 1 left and a mainframe.

In the left frame i have a form that runs a query on a table from my database and shows it in de mainframe.
When i select then one row to show me the details also in the mainfraim and push then the back button, i got this message "Page has expired". is it not possible that when i puch the back button i'll get back my first query results in the mainframe.

You usually get that when you use a form method of "post" instead of "get".

Is that the case here?

In truth not always. In practise probably never.

The purpose of the back button is to show a previously rendered page (sorta).

If the page is created by POSTing data, the data is no longer available.

I've used several online banking systems (which I am assuming are very secure). They all comment on the use of the back button as being something that will not work inside the secure pages.

I've found the same for all my PHP/MySQL forms.
