NGINX http to https with exceptions - nginx

Question

We have 2 files in our nginx/sites-available/ folder. The odoo-80 and the odoo-443. How can we add a exception for 1 specific path without creating a loop? If we add the exception to the 443 file it redirects back to the 80 file and opposite... Im normally working with apache and not nginx so I would be very happy for some help!
To summ up: we want this path: /pos/web to run with http and all the rest with https.
odoo-80 file
server {
listen 80;
server_name odoo.server.com;
access_log /var/log/nginx/odoo.access.log;
error_log /var/log/nginx/odoo.error.log;
location / {
rewrite ^/(.*) https://odoo.server.com:443/$1 permanent;
}}
Odoo-443 file
#odoo server
upstream odoo {
server 127.0.0.1:8069;
}
upstream odoochat {
server 127.0.0.1:8072;
}
server {
listen 443;
server_name odoo.server.com;
proxy_read_timeout 720s;
proxy_connect_timeout 720s;
proxy_send_timeout 720s;
# Add Headers for odoo proxy mode

You can declare a location {} in your odoo-80 file, this should override the catch-all you have in place so it shouldn't send it to 443 in the first place.
server {
listen 80;
server_name odoo.server.com;
access_log /var/log/nginx/odoo.access.log;
error_log /var/log/nginx/odoo.error.log;
location ~ ^/pos/web {
proxy_redirect off;
proxy_pass http://odoo;
}
location / {
rewrite ^/(.*) https://odoo.server.com:443/$1 permanent;
}
}
Also, what Richard Smith mentioned, add the same block to 443 just in case someone types in https:// and heed his call re: HSTS (which I doubt is setup)
"we" should also be posting on Serverfault by the way :D
