pun_proxy_handler

This handler proxies a user’s traffic to his/her backend PUN listening on a protected Unix domain socket. If the user’s PUN is down, then this handler will attempt to start up their PUN process.

Note

This handler requires the nginx_handler to initialize an app’s NGINX configuration file if the app does not exist in the backend PUN.

Configuration

Configuration is handled by setting CGI environment variables within the Apache configuration file with the following format:

SetEnv ARG_FOR_LUA "value of argument"

OOD_USER_MAP_CMD

Absolute path to the script that maps the authenticated user name to the local user name. See ood_auth_map.

OOD_USER_ENV

Optional

Points to the CGI environment variable that stores the authenticated user name if different than REMOTE_USER.

OOD_MAP_FAIL_URI

Optional

URL the user redirected to if we fail to map the authenticated user name to a local user name. If not specified then return an error message to the user.

OOD_PUN_STAGE_CMD

Absolute path to the script that stages the PUN processes. See nginx_stage.

OOD_PUN_SOCKET_ROOT

Absolute path to the directory that contains the user directories with the corresponding Unix domain socket files. Under a default installation this should be /var/run/nginx.

OOD_PUN_MAX_RETRIES

Maximum number of attempts to start up a user’s PUN before giving up and displaying an error to the user. Recommended value is 5.

OOD_NGINX_URI

The base URI that namespaces the nginx_handler from the other handlers. Recommended value is /nginx.
