# StoRM Frontend configuration file reference
The Frontend component relies on a single configuration file that contains all the configurable parameters. This file is:
/etc/storm/frontend-server/storm-frontend-server.conf
containing a list of key-value pairs that can be used to configure the Frontend server. In case a parameter is modified, the Frontend service has to be restarted in order to read the new value.
Currently, the Frontend’s configuration parameters can be divided per section as follows.
