Hi, I know this should be a very simple problem to solve but I'm not able in any way. I'm spending several days trying every solution I can find on many forum but nothing.
What I need is just to add a parameter at the end of an URL. Actually I'm using Grafana behind Ngnix and what I need is as following:
I can have two situation:
1) The required URL is https://www.mydomain.com/mygraf/login
If so, I need to redirect/rewrite the URL as https://www.mydomain.com/mygraf/d/uiehy96ta/mydash?orgId=1&kiosk
2) The required URL is https://www.mydomain.com/mygraf/whatever (i.e. https://www.mydomain,com/mygraf/d/uiehy96ta/mydash?orgId=1)
If so, I need just to add &kiosk in order to rewrite the URL as https://www.mydomain.com/mygraf/d/uiehy96ta/mydash?orgId=1&kiosk
(if &kiosk is already within the URL, of course it's ok and I have nothing to add/change)


If I try copy paste directly on the browser it works as espected, and I just would like replicate it via Nginix configuration.
Here is mine:
server {
listen 80;
server_name mydomain.com www.mydomain.com;
return 301 https://mydomain.com$request_uri;
}
server {
listen 443 ssl http2;

index index.html index.htm index.php;

error_log /var/log/nginx/mydomaincom.error.log;
}
# ---------------- Grafana

}

Thanks a lot to all
