browser-reload/forms and browser/cache

fazer75

hi...

a bit of an undefined question but whatdaheck.. somebody might give me a clue what to do...

when i use forms and send something to $php_self, it workes fine... but if i press reload afterwards... a popup appears asking me to repost, and after canceling that popup, i get a message like page not valid no more. annoying like hell.. is there a way get around this???

i also have aother big problem with "my" site.. even if i press reload on some pages and have these metatags:
<META NAME="ROBOTS" CONTENT="NOINDEX,NOFOLLOW">
<META HTTP-EQUIV="Cache-Control" CONTENT="No-Cache">
<META HTTP-EQUIV="Pragma" CONTENT="No-Cache">
<META HTTP-EQUIV="Expires" CONTENT="0">
the same page appears??? and wen it comes to pictures that are changed (with the same name) i have to empty the browsers cache... or add a ?random=143413 in the picture-url.

Is there a smoooooth way to solve these BIG problems that im having??

have a nice day!

Ok, first of all the form posting.

As far as the browser is concerned, there has been data sent to the page that you are reloading, therefore it expects to have to be able to send data to that page for it to do anything.
If you hit cancel, the browser thinks that the page will not do anything, therefore it displays a message because it hasnt sent any data.
You possibly may get around this by using the 'Back' button, rather than reload.

The second problem, is not just down to the meta tags in your page, it will also be to do with the browser itself, and the web server (also, you may be going through a transparent proxy server).

The upshot of this is that there is nothing really that you can do.

(if i'm talking rubbish, will someone please correct me)

If you are generating the form page through a php page then you could try adding this to the top of your php script:

// to retain cache in IE back button
header("Cache-Control: Public");

This tells the browser(IE) to retain the cache. It may not work in all cases though.

If the form is being submitted without seeing a php page first then this may not work for you.
