gobot/nginx-config.md

Let's assume the following:

• Your nginx is running under the document root of /var/www/
• You install the gobot binary in that directory
• /lib and /templates are placed under /var/www/lib and /var/www/templates, respectively
• gobot is set to run on localhost at the default port 3000
• Besides serving the files statically via nginx (Go can do it too, but nginx is more efficient), you wish to use nginx's internal super-fast and efficient caching system for the replies coming from Go; a possible place to store those cache files is under /var/cache/nginx/

Then the configuration below is what you need to add for that server (or virtual host), replacing, of course, the root directives with /var/www/lib and /var/www/templates.

You can, of course, put those directories elsewhere (e.g. a read-only directory away from the main server, whatever) but then remember to update PathToStaticFiles in config.toml. Currently those need to be in the same server, but, who knows, I might add the extra logic to host those static files elsewhere. For my purposes, nginx is already super-fast...
