forms and back or refresh

[smindel]

hi there,

i coded some kind of a bulletin board. members can add, change or delete articles. everything works fine, but...

if i choose an article from a list, i get a form with the article details (headline, short text, long text) filled in. if i press "delete", the article is deleted, but when i hit the back button, i get back to the form with the article which doesnt exist anymore.

or if i alter the details and press "save changes" the form is being processed correctly, but if i go back i get the old version of the article.

that might be confusing for the user.

i guess thats because the php script is not being processed once more and so i get a cached version of the form.

meta-tags like:
<meta http-equiv="expires" content="0">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="pragma" content="no-cache">
dont make it

can anybody tell me how to force the browser to request the form again so i can catch the error?

helpless

but if i go back i get the old version of the article.

How do you back then?

back buttons suck

anyway set up the page with the nocache pragma and see if that helps.

@: theres no need to go back actualy, because after you changed or deleted an article you get back to the list, but users may want to go back using the back button and i want to catch errors and prevent user from being confused.

@: as i wrote, that doesnt help. the page is being loaded from cache anyway, ignoring meta tags. that seems to be standard behaviour.
