This is the Nginx configuration tool that is embedded within the portal. Here are the settings available with the relevant references to the Nginx wiki.

Nginx setting nameScopeDescription
error_pageGloballyOverrides the error page that is shown when there is a 5xx error reaching the origin server or if the request limit is reached. Operator will be presented a textbox to enter the HTML code for the error. This lets the operator’s customer’s visitors see a prettier page than just “Nginx 504 gateway timeout”
limit_rate
limit_rate_after		Per CDN SiteLimits the speed of any one request of a CDN Site. This is not a limit across the whole CDN Site, but a limit per request. This can be used to limit the speed of a progressive download or pseudo streaming CDN Site, in order not to waste bandwidth serving the video faster than its bitrate.
limit_req
limit_conn		Per Edge ServerSets the connection limit (simultaneous and rate) to handle abusive clients.

This is a global setting but takes effect per server.
proxy_cache_keyPer CDN SiteSet the cache key, which is how a request is stored and looked up in cache. Awesome things can be done like setting a cache key that ignores certain elements of the url.

But for now, the options presented to the operator are:
  • $host$request_uri
  • $proxy_host$request_uri
  • $host$filename
  • $proxy_host$filename
proxy_read_timeout
proxy_connect_timeout		Per CDN SiteIncrease or lower the timeout setting for a CDN Site when connecting to its origin.

A lower timeout allows quicker recovery from a dead origin, but at the same time it will be more sensitive to performance fluctuations.

All the settings above are optional, if none are specified, the settings are loaded from the Edge server's Nginx configuration file.
