Hi !
I got a pretty ennoying problem, I have boost activated, pages are correctly generated & served.
But when the user comes back, it gets the content from the browser cache instead of the newly generated "boost html file". You have to hit CTRL F5 to get the new content to be loaded.
I modified htaccess (as suggested here: http://drupal.org/node/1074304 & here http://drupal.org/node/1070232

### BOOST START ###
  AddDefaultCharset utf-8
  FileETag MTime Size
  <FilesMatch "(.html|.html.gz|.xml|.xml.gz|.json|.json.gz)$">
    <IfModule mod_headers.c>
      Header set Expires "Sun, 19 Nov 1978 05:00:00 GMT"
      #Header set Cache-Control "no-store, no-cache, must-revalidate, post-check=0, pre-check=0"
    </IfModule>
  </FilesMatch>

but no chance ! http://www.internationalcooperationgeneva.org/ still need the CTRL F5 to be shown with the latest content.

Any suggestion ? Hints ... very very very welcome .. I get crazy with this ;-)

mod_headers

it sounds crazy, but check and make sure mod_headers is enabled.

the idea behind the header directives in the boost .htaccess to to prevent exactly the problem you're experiencing, and lacking mod_headers is one way that could happen.

you can use firebug (or the analogous tool for your preferred browser) to see what headers are being set, and whether or not a particular request is being served from cache.

you may need to clear your browser cache each time you edit .htaccess to make sure you're starting fresh, and don't have old rules saved in a local cache.

you should check the source to make sure that boost is actually working - maybe you're not getting pages from boost after all, and the problem is with .php requests and not .html requests.

good luck!

Hello FireBus ! I'm sure

Hello FireBus !

it seems that "Header set Expires" is not adequat, max-age needs also to be specified :

  AddDefaultCharset utf-8
  FileETag MTime Size
  <FilesMatch "(.html|.html.gz|.xml|.xml.gz|.json|.json.gz)$">
    <IfModule mod_headers.c>
      Header set Expires "Sun, 19 Nov 1978 05:00:00 GMT"
      Header set Cache-Control "max-age=0, no-store, no-cache"
    </IfModule>
  </FilesMatch>
   <FilesMatch ".(flv|gif|jpg|jpeg|png|ico|swf)$">
    <IfModule mod_headers.c>
      Header set Cache-Control "max-age=2592000"
    </IfModule>
   </FilesMatch>
  <FilesMatch ".(js|css|pdf|txt)$">
    <IfModule mod_headers.c>
      Header set Cache-Control "max-age=604800"
    </IfModule>
   </FilesMatch>
