same as #11143 ?

I claim this is not the same issue as #11143 because after I switched twice to English I can't visit my dutch home page anymore unless I first clear the browser cache!
Visits from my browser will always go to the http://www.handysplace/en language even if I visit http://www.handysplace.nl/nl it will rewrite to /en.

the problem is the cached 301 redirect right?

Same reason,

• but this time more problematic effect, issue #11143 is rather minor
• language switching of home-page, is impossible if you enable "Remove URL Language Code", which removes language code for default language

at least if you are at a non-home page url the language switching will work,

so in great majority of web-sites, users will be able to switch language

• thus it is not urgent, but really needs to be fixed
• the bad is that as time passes more websites are telling browsers to cache the home page redirect permanently (if website has enabled "Remove URL Language Code")

to see the effect look at the picture

you visit /nl/
it is redirected permanently to /
which then redirects permanently to /en/

@Handy84
Please, see my above description and check the parameter,

Please note that after disabling the parameter,
the effect will not go away
unless you force the browser to clear its cache

i think there are two options:
1. Send HTTP header to remove browser cache from 301 redirect
2. Use a 302 or 303 redirect (doesn't cache) but less SEO

Anyway the changes are in here https://github.com/joomla/joomla-cms/blob/staging/plugins/system/languagefilter/languagefilter.php#L397-L402

For 301 with no cache i think prepending this lines would work

$this->app->setHeader('Cache-Control', 'no-store, no-cache, must-revalidate, post-check=0, pre-check=0');
$this->app->setHeader('Expires', 'Mon, 26 Jul 1997 05:00:00 GMT');
$this->app->sendHeaders();

I have implemented those lines and it's working, big thumbs up !

please test #11161

I have the same problem with Joomla 3.6.4, but i have a modified htaccess with:

# EXPIRES CACHING #
<IfModule mod_expires.c>
    ExpiresActive On
    ExpiresDefault "access plus 2 days" <------ AFTER REMOVE IT, PROBLEM SOLVED.
    ExpiresByType image/jpg "access plus 1 year"
    ExpiresByType image/jpeg "access plus 1 year"
    ExpiresByType image/gif "access plus 1 year"
    ExpiresByType image/png "access plus 1 year"
    ExpiresByType text/css "access plus 1 month"
    ExpiresByType application/x-font-woff "access plus 1 month"
    ExpiresByType application/pdf "access plus 1 month"
    ExpiresByType video/mp4 "access plus 1 month"
    ExpiresByType text/js "access plus 1 month"
    ExpiresByType text/javascript "access plus 1 month"
    ExpiresByType application/javascript "access plus 1 month"
    ExpiresByType application/x-javascript "access plus 1 month"
    ExpiresByType application/x-shockwave-flash "access plus 1 month"
    ExpiresByType image/x-icon "access plus 1 year"
</IfModule>

If i remove "ExpiresDefault "access plus 2 days"" the problem is solved.
How can i be more specific with expires without breaking the multilanguage cache control?

Thanks

if you are caching all html pages in browser for 2 days you will have issues more problematic than this.

Anyway you can't change the joomla cache http headers for 301/302/303 redirects with your webserver for the language filter to work fine.

You are right, this is an old setup not valid with Joomla. Thanks!
