Companion to #756. The web server ships three cache-control environment variables built on the same mechanism; #756 documents the
FlutterRouteone, and this adds the other two on their own pages:SERVERPOD_WEB_SERVER_STATIC_CACHE_CONTROLon the Static files page, next to the cache-control helpers it substitutes for.SERVERPOD_WEB_SERVER_SPA_CACHE_CONTROLon the Single-page apps page, including the two SpaRoute-specific rules: the fallback file is always served without aCache-Controlheader, and the static variable does not apply toSpaRoute.In all three cases an explicit
cacheControlFactorytakes precedence over the environment variable.
