Re: previous page button of browser opening on-rev server page
Thank you Dave. I found out that Safary needs an additional attribute in the body tag : body onunload= to reload the page. So, here it is the code working for Firefox, Safari and IE, both with PHP and LiveCode server. PHP ?php header(Cache-Control: no-cache, no-store, must-revalidate); header(Expires: Fri, 30 oct 1998 14:18:41 GMT); ? html head meta http-equiv=Content-Type content=text/html; charset=UTF-8 / titleDocumento senza titolo/title /head body onunload= ?php echo date(Y:m:d-H:i:s); ? /body /html LIVECODE ?rev put header Cache-Control: no-cache, no-store, must-revalidate put header Expires: Fri, 30 oct 1998 14:18:41 GMT ? html head meta http-equiv=Content-Type content=text/html; charset=UTF-8 / titleDocumento senza titolo/title /head body onunload= ?rev put the long time ? /body /html All the best.

Re: previous page button of browser opening on-rev server page
Thank you all. Trying to get rid of the browser cache setting the
proper headings (as Shao Sean suggested) , I came up with these 2
solutions:
PHP:
?php
header(Cache-Control: no-cache, must-revalidate);
header(Expires: Fri, 30 oct 1998 14:18:41 GMT);
?
?php
$dateTime = date(Y:m:d-H:i:s);
function getDateTime() {
global $dateTime;
return $dateTime;
}
?
html
head
/head
body
?php echo getDateTime() ?
/body
/html
LIVECODE ... much easyer ;-)
?rev
put Cache-Control: no-cache, must-revalidate return Expires:
Fri, 30 oct 1998 14:18:41 GMT into MYHEADERS
set the httpHeaders to MYHEADERS
put the long time
?
HOWEVER, the first solution (PHP) sets the heathers properly but still
when I move back and forth with the buttons of the browser I get the
old time (cache). The second one (LiveCode) does NOT set the headers
properly (is it a bug?) and the page remains in the browser cache.
Any idea? All the best

Re: previous page button of browser opening on-rev server page
I don't think setting the 'httpHeaders' will do what you want - that's meant
for getting a URL or posting to a it from within your LC script.
Try this instead (untested, but should do the trick, I think):
?rev
put header Cache-Control: no-cache, must-revalidate
put header Expires: Fri, 30 oct 1998 14:18:41 GMT
put the long time
?

Not really a fair comparison. The following php script will do the same as your
Livecode script:
?php
header(Cache-Control: no-cache, must-revalidate);
header(Expires: Fri, 30 oct 1998 14:18:41 GMT);
echo date(Y:m:d-H:i:s);
?
Not so different. :-)

Re: previous page button of browser opening on-rev server page
Thank you all. So, there is a property ( header ) only for the on-rev server environment? In fact I can not use this property in the IDE (I get a compilation error) and it does not exists in the LC documentation (version 4.6.0). Are there other undocumented properties suitable only to the server environment? Actually the script suggested by Jan works, and I get a page with 2 new headers. However, for some reasons, the browser do not reload the page. Dave, you are right, I was unfair with PHP... still, at least put the long date is pretty elegant. All the best.

Dave, you are right, I was unfair with PHP... still, at least put the long date is pretty elegant. I should apologize as I butted in without following the earlier mails. But your problem has got me interested as I didn't know the back button doesn't respect the cache settings. I found this solution using no-store that appears to work for Firefox but not Safari. Can't test IE right now. For PHP... header(Cache-Control: no-cache, no-store, must-revalidate); header(Expires: Fri, 30 oct 1998 14:18:41 GMT); echo date(Y:m:d-H:i:s); For Livecode (not tested) put header Cache-Control: no-cache, no-store, must-revalidate put header Expires: Fri, 30 oct 1998 14:18:41 GMT put the long time Cheers Dave ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Re: previous page button of browser opening on-rev server page
Hi Mark, when I go back with then previous page button of the browser, the cgi does not run again. The browser simply return the HTML recorded in the browser cache. I tried with Safary and with Firefox; both of them do the same thing. However, if I empty the cache before returning to the previous page, the browser runs the cgi again.

Thank you all. Trying to get rid of the browser cache setting the

solutions:
FIRST ONE WITH PHP
?php
header(Cache-Control: no-cache, must-revalidate);
header(Expires: Fri, 30 oct 1998 14:18:41 GMT);

?php
$dateTime = date(Y:m:d-H:i:s);

THE SECOND ONE WITH LIVECODE ... much easyer ;-)
?rev
put Cache-Control: no-cache, must-revalidate return Expires:
Fri, 30 oct 1998 14:18:41 GMT into MYHEADERS
set the httpHeaders to MYHEADERS
put the long time
?
HOWEVER,
the first one (PHP) set the heathers properly but still I get the old
time in the page (cache) when I move back and forth with the buttons
of the browser.
The second one (LiveCode) does NOT set the headers properly (is it a
bug?) and the page remains in the browser cache.
Any idea?
