As Quentin exlplain this meta tags are ignored by the browser.
<meta content="no-cache" http-equiv="Pragma"></meta>
<meta content="no-cache, no-store, must-revalidate" http-equiv="Cache-Control"></meta>
<meta content="0" http-equiv="Expires"></meta>
So this is what worked for me to disable the cache in all browsers.
From perl
Use CGI;
sub set_new_query() {
$query = CGI->new();
print $query->header(
-expires => 'Sat, 26 Jul 1997 05:00:00 GMT',
-Pragma => 'no-cache',
-Cache_Control => join(', ', qw(
private
no-cache
no-store
must-revalidate
max-age=0
pre-check=0
post-check=0
))
);
}
An alternative in Apache is to add to httpd.conf:
LoadModule headers_module modules/mod_headers.so
<FilesMatch "\.(html|htm|js|css|pl)$">
FileETag None
<ifModule mod_headers.c>
Header unset ETag
Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"
</ifModule>
</FilesMatch>
