This is an nginx proxy for deployment on Cloud.gov that proxies content from an S3 bucket. It works well with Federalist websites.
The proxy has two configurable routing paths. The first path is to route all requests from a BASE_DOMAIN (such as 18f.gsa.gov) to a specific path on a S3 bucket, defined by PROXY_ROOT (such as http://federalist.18f.gov.s3-website-us-east-1.amazonaws.com/site/18F/18f.gsa.gov, which in this case is the origin of a Federalist site).
The second is that all other non-BASE_DOMAIN requests will route to PROXY_ROOT/site/$domain, where $domain is the domain of the request. For examples, https://example.gov/about/ would route to PROXY_ROOT/site/example.gov/about/. This enables the proxy to function as a multi-tenent origin proxy for Federalist sites.
Deploy to Cloud.gov by setting the desired environment variables and pushing with cf push.
Configuration is handled by environment variables. The following variables are available:
BASE_DOMAIN: Requests on this domain are routed to the root ofPROXY_ROOTPROXY_ROOT: The URL from which requests should be proxied; may include subdirectoriesPORT: The port on which the server should listen; set automatically by cloud.govGZIP_COMPRESS: Iftrue, responses will be GZIP'd; False by default since Federalist does this automaticallyCACHE_EXPIRES: The value for theexpiresheader
