Global Init Handler" ?> This is executed in the 'parent' process, so its effects are truly global. In Rivet, we only add a string to the Apache version:
MODULE_VAR_EXPORT void
Rivet_InitHandler(server_rec *s, pool *p)
{
#ifndef HIDE_RIVET_VERSION
    ap_add_version_component("Rivet / "RIVET_VERSION);
#else
    ap_add_version_component("Rivet");
#endif /* !HIDE_RIVET_VERSION */
}
