[ #118 ] nginx -> Django fcgi SSL! Permalink

nginx, Django Added a year and a bit ago and last edited a year and a bit ago

I have setup nginx as my webserver. It acts as a proxy in front of the django site running it's own fcgi server:

# from within your django project, run the fcgi server as such (must have flup installed)
/usr/bin/env python manage.py runfcgi host=127.0.0.1 port=8080 --settings=settings

I use SSL middleware in my django site to automatically redirect to https:// for certain URLs - mainly /admin/

My nginx.conf has to have two server configs, one for HTTP and one for HTTPS:

server {
    listen 80;
    server_name notareal.com.net.org;
    location /media {
        root /home/www/projectroot;
    }
    location / {
        fastcgi_pass 127.0.0.1:8080;
        fastcgi_param SERVER_NAME $server_name;
        fastcgi_param SERVER_PORT $server_port;
        fastcgi_param SERVER_PROTOCOL $server_protocol;
        fastcgi_param PATH_INFO $fastcgi_script_name;
        fastcgi_param REQUEST_METHOD $request_method;
        fastcgi_param QUERY_STRING $query_string;
        fastcgi_param CONTENT_TYPE $content_type;
        fastcgi_param CONTENT_LENGTH $content_length;
        fastcgi_pass_header Authorization;
        fastcgi_intercept_errors off;
    }
}
server {
    listen 443;
    ssl on;
    ssl_certificate /usr/local/nginx/ssl/server.crt;
    ssl_certificate_key /usr/local/nginx/ssl/server.key;
    keepalive_timeout 70;
    server_name notareal.com.net.org;
    location /media {
        root /home/www/projectroot;
    }
    location / {
        fastcgi_pass 127.0.0.1:8080;
        fastcgi_param SERVER_NAME $server_name;
        fastcgi_param SERVER_PORT $server_port;
        fastcgi_param SERVER_PROTOCOL $server_protocol;
        fastcgi_param PATH_INFO $fastcgi_script_name;
        fastcgi_param REQUEST_METHOD $request_method;
        fastcgi_param QUERY_STRING $query_string;
        fastcgi_param CONTENT_TYPE $content_type;
        fastcgi_param CONTENT_LENGTH $content_length;
        fastcgi_param HTTP_X_HTTPS on;
        fastcgi_pass_header Authorization;
        fastcgi_intercept_errors off;
    }
}

The magic line is fastcgi_param HTTP_X_HTTPS on; now we can modify our SSL redirection middleware to check for HTTP_X_HTTPS instead of HTTP_X_FORWARDED_SSL (or you could use HTTP_X_FORWARDED_SSL if you wanted, just change the nginx.conf)

And it all works well!

[ #26 ] Tag Clouds and Caching Permalink

Django, Git Added nearly two years ago

On the right you will notice a new tag cloud. I wrote a tag_cloud templatetag in Django for it. Generating a tag cloud involves a little calculation, so I cached it using Django 1.0's Template Fragment Caching. It lets me wrap anything in a template with a cache templatetag, specifying seconds to cache for.

I have two separate cache settings, one for dev and one for prod environments (in their corresponding settings files.) They are using Django's filesystem caching - so the cache is just stored on disk. I am storing the cache in a subdirectory of the codebase, but I don't want the cache being carried around in the Git repo, so I added:
