I have the following configuration for vhost:
server {
listen 80;
server_name www.mydomain.com;
#redirect www to non-www
rewrite ^/(.*) http://mydomain.com/$1 permanent;
}
server {
listen 80;
server_name mydomain.com;
access_log /home/mydomain/log/access.log;
error_log /home/mydomain/log/error.log;
location / {
root /home/mydomain/public_html/;
index index.php index.html;
expires 30d;
#stop image and files hotlinking
location ~* ^.+\.(gif|jpg|png|swf|flv|rar|zip|jpeg|css)$ {
valid_referers none blocked mydomain.com www.mydomain.com
*.google.com *.yahoo.com;
if ($invalid_referer) {
return 444;
}
}
#joomla sef url's
if (!-e $request_filename) {
rewrite ^(.*)$ /index.php?q=$1 last;
break;
}
}
if ( $args ~ "mosConfig_[a-zA-Z_]{1,21}(=|\%3d)" ) {
set $args "";
rewrite ^.*$ http://$host/index.php last;
return 403;
}
if ( $args ~ "base64_encode.*\(.*\)" ) {

return 403;
}

return 403;
}

I tried what you suggested but it doesn’t work or I didn’t add it
properly.

I want to redirect all calls to http://mydomain.com/index.php to http://mydomain.com to avoid duplicate pages.I use this
if ($request_uri ~* “^/index.php??$”) {
    rewrite ^.*$ http://$host? permanent;
}
but it doesn’t seem to work properly. Although it redirects I cannot login or logout anymore in Joomla, it simply redirect to homepage without login or logout. What am i missing here ? How do i do this properly ? Of course if i remove that everything i fine, it works for example for home.html but not for index.php.
Thank you.
The right way is to use
   location = /index.php {
     rewrite ^ http://$host? permanent;
   }
However, if you have the following configuration:
   location / {
     index index.php;
   }
   location = /index.php {
     rewrite ^ http://$host? permanent;
   }
then the “/” request will be internally redirected to “/index.php”.
Therefore you should use something
   location = /index.php {
     if ($request_uri = /index.php) {
       rewrite ^ http://$host? permanent;
     }
     …
   }
How do login and logout URLs look ?
