Field Detail

NUXEO_WEBENGINE_BASE_PATH

static final String NUXEO_WEBENGINE_BASE_PATH

This variable is used in a proxy setting. The proxy should send a header with this name. Webengine will assume that the base path of the application is this value.

If your application is on server localhost:8080/nuxeo/site/myapp and you proxy it via mysite.com/myapp, then the header should have an empty string value.
