Reload/refresh web page

I need to add some coding to a web page that forces a reload from the
server every time the page loads, no matter where the user came from.

I already have the following meta tags but that does not do what is
required.


I also cannot use the full URL, as has been recommendedon the web, as
these pages could be at various of my users branches and they could well
have their own URLs.
ie No standard URL available.

My first thought was to add refresh within a onload but this would be
daft as one would end up in a permanent loop.

Please make suggestions.

That would refresh after 600 seconds. Not quite what I want. I want to

Re: Reload/refresh web page

I have seen references to using the "refresh" without the content.
could this be incorporated into an onload event?

www.html-reference.com says that Indicates the document displays for a specified amount of time before
switching to a new URL. The full absolute URL must be specified.

Therefore that is not on.>

Try that with true setting and you end up in the loop I spoke of in my
original email
and yes the page I want reloaded is dynamic and every time it displays I
want it to be retrieved from the server, but how?

RE: Reload/refresh web page

Can we ask why you need a reload every time? Maybe there's a better
approach?

But, if you need to reload the first time someone hit's a page, add a
querystring value to the url and track it. If the value isn't there (
if(!isset($_GET['reload'])){// do a reload} ), then do a header:
location call. Otherwise, it's the second time to the page, so let it
load...

Re: Reload/refresh web page

I'll go with Bill's suggestion. Just track whether the page has already
been loaded.

It is but the page I need to reload is a dynamic page that may be used
as a menu to call another php that would be used to update a database
contents of which were displayed on the original page and on return to
the dynamic page I want this new data to be included.

RE: Reload/refresh web page

Aaah, so it's a caching issue then. Is that particular content using
PHP's caching mechanism or is it simply the browser's cache settings
mucking things up?

AJAX techniques run into the browser cache issue all the time (not that
your doing anything with AJAX here). One way to get around this is by
putting a random value in the querystring when calling a script by and
HTTP JavaScript call. Maybe by borrowing this concept and put a random
value in the querystring (that servers no purpose) will fool the browser
and load the new content.

You are correct, it is the broser, and I have no control over which
browser they are using or how that browser is configured.

Re: Reload/refresh web page

If you are allready using ajax, then don't request the page with get
paramater but using POST. The script you are calling must have headers
set to expire immidiatly ala
header('Cache-Control: max-age=0, must-revalidate');
?>

RE: Reload/refresh web page

Do a search with AJAX CACHE ISSUE. There are tons of links and it seems
to be directed mostly at Internet Explorer.

At it simplest, when your user is getting sent back to the page to view,
make sure the URL has an extra value in the querystring (if you're
passing stuff back already) such as:
http://www.somesite.com/originalpage.php?random=3Dnco8agoafn vpqfq4iu=20

You can generate an random value pretty easily - don't have any code
right in front of me at the moment.

Thank you all for your suggestions and help.
I have decided, as the pages are all created in PHP, to go with
URL?Diva=rand() or URL?UID=&Diva=rand() and it
seems to work.
Let us now see how idiot proof it is and give it to the users and see if
God has made a better idiot.
