Securing Nginx with SSL - ssl

Question

I´m securing an Nginx server with SSL and I have a question. I have two virtual servers one for http listening in port 80 and the https listening in 443 like this:
# HTTP server
server {
listen 80;
server_name localhost;
...
# many configuration rules here for caching, etc
}
# HTTPS server
server {
listen 443 ssl;
server_name localhost;
...
}
The question is, do I need to duplicate all the configuration rules that I have in the http version into my https version? Is there any way to avoid duplicate all these rules?
UPDATE
I´m trying to config with an include according to #ibueker answer. Looks easy but somehow is not working. Does the include need to be inside a location? Example attached:
# HTTP server
server {
listen 80;
server_name localhost;
...
include ./wpo
}
Where wpo file is in the same path, and it´s like:
# Expire rules for static content
# RCM: WPO
# Images
location ~* \.(?:jpg|jpeg|gif|png|ico|cur|gz|svg|svgz|mp4|ogg|ogv|webm|htc)$ {
root /home/ubuntu/env/production/www/yanpy/app;
expires 1w;
add_header Cache-Control "public";
}
# CSS and Javascript
location ~* \.(?:css|js)$ {
root /home/ubuntu/env/production/www/yanpy/app;
expires 1w;
add_header Cache-Control "public";
}
# cache.appcache, your document html and data
location ~* \.(?:manifest|appcache|html?|xml|json)$ {
root /home/ubuntu/env/production/www/yanpy/app;
expires -1;
}

You can put them in another file and include them for both server blocks.
include /path/to/file;
