		epriestleyAuthorUnsubmitted Not Done Inline Actions Yeah. The "request base URI" is "the base URI which is implied by the request headers", and does not override "phabricator.base-uri". A better name might be "setFallbackBaseURI()" or something, maybe. Calls like getURI() and getProductionURI() basically go: if (phabricator.base-uri is set) { use that; } if (the "request base URI" is set) { use that; } throw an exception; epriestley: Yeah. The "request base URI" is "the base URI which is implied by the request headers", and…
