Page has expired -problem

[Jarkko Kähkönen]

Hi!
I have Windows XP&IE6.0.2... (SP1).

I'm coding one project with PHP.
I get "Warning: Page has Expired" when I try to get back to the "POSTed
page" (page whither moved from FORM-page).

Better explanation:
- Pages are:
* Page A: Front-page
* Page B: Page where is www-FORM

#1.) From Page "A" I move to the page "B" by clicking link on page "A" and I
fill the form's fields
#2.) Then I click SUBMIT-button and I moved back to the page "A"
#3.) I move to the page "B" by clicking link on page "A"
#4.) I click "BACK"-button from browser
#5.) I got "Warning: Page has Expired"


I want that when I click BACK, I will be moved to the page "A" straightly
without warning
(of course then post-data can't get re-sent)

Got any idea how in PHP I can prevent this warning?

Thanks in advance!

Best regards,
Jarkko Kähkönen

Stop outputting "This page has already expired" headers in the first page.

This is behaviour by design. At other times at other sites you 'll be
thankful for it. Especially when combined with get variables, websites may
still re-process your form when the page is reloaded.
The workaround is to skip the resulting page in the history build-up of the
browser. Post your data to a page which outputs some http_equiv redirect or
location.replace to a page which will allow returns.
