Nginx - Redirect HTTPS back to HTTP when leaving a secured page - node.js

Question

I have Nginx in front of a Node.js app. I have it set up so that if the url has /account in it, it'll redirect to HTTPS. My question is - how do I set it up so that if the user leaves the /account url (clicks a link to go to the home page), it'll get sent back to HTTP?
Here's my ngnix.conf:
worker_processes 1;
error_log logs/error.log;
pid logs/nginx.pid;
events {
worker_connections 128;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
server_tokens off;
#keepalive_timeout 0;
keepalive_timeout 65;
tcp_nodelay on;
proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
gzip on;
server {
listen 80;
server_name localhost;
location / {
proxy_set_header x-path $uri;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://127.0.0.1:3000;
proxy_redirect off;
}
location /account {
rewrite ^(.*) https://$host$1 permanent; #redirect to https
}
error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
server {
listen 443;
ssl on;
ssl_certificate ssl/server.crt;
ssl_certificate_key ssl/server.key;
location / {
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-M-Secure "true";
proxy_redirect off;
proxy_max_temp_file_size 0;
proxy_pass http://127.0.0.1:3000;
}
}
}
Thanks in advance for any assistance.

This is untested.
server {
listen 443;
ssl on;
ssl_certificate ssl/server.crt;
ssl_certificate_key ssl/server.key;
location /account/ {
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-M-Secure "true";
proxy_redirect off;
proxy_max_temp_file_size 0;
proxy_pass http://127.0.0.1:3000;
}
location / {
rewrite ^(.*) http://$host$1 permanent; # redirect to http
}
}
