  "message": "Avoid multiple auth requests for Git/HTTP access\n\nWhen authenticating incoming Git calls over HTTP\nthe BasicAuth filter was called 3 times per call\ntriggering multiple authentications against the backend.\n\nExample: Git protocol v1 triggering 2x HTTP calls,\none for refs-advertisement and another for upload-pack\nwas generating 6x authentication requests.\n\nWhen the backend is Gerrit\u0027s HTTP password authentication\nthe operation is quite fast making the impact of the extra\nauthentications negligible. However, when authenticating\nagainst a slower backend (e.g. corporate LDAP with groups\nresolution) the extra authentication calls were introducing\nunneeded latency and generating extra workload to the\nLDAP server.\n\nNOTE: It is still not possible to have one single authenticated\nsession for multiple HTTP calls, because of the lack of\nsupport for GerritAccount cookie from the ProjectBasicAuthFilter.\nThe next follow-up change is focused in solving that problem\nspecifically, bringing the number of authentication requests\nto one.\n\nBug: Issue 14497\nChange-Id: Ibe41df0357b6be10bcdf0bd1f5a1b6160c34d4a4\n",
