| 111 | * Do not set this until it has been set in the backend. |
| 112 | * - canShellboxGetTempUrl : Set this to true to generate a TempURL allowing Shellbox to |
| 113 | * directly fetch files from Swift. swiftTempUrlKey should be set. |
| 114 | * - shellboxIpRange : An IP range string to use when generating TempURLs for Shellbox. |
| 115 | * Specifying this will improve security by preventing exfiltrated |
| 116 | * TempURLs from being usable outside the server. |
| 117 | * - swiftStorageUrl : Swift storage URL (overrides that of the authentication response). |
| 118 | * This is useful to set if a TLS proxy is in use. |

| 120 | * - base : base of hash characters, 16 or 36 |
| 121 | * - levels : the number of hash levels (and digits) |
| 122 | * - repeat : hash subdirectories are prefixed with all the |
| 123 | * parent hash directory names (e.g. "a/ab/abc") |
| 124 | * - cacheAuthInfo : Whether to cache authentication tokens in APC, etc. |
| 125 | * If those are not available, then the main cache will be used. |
| 126 | * This is probably insecure in shared hosting environments. |
| 127 | * - rgwS3AccessKey : Rados Gateway S3 "access key" value on the account. |
| 128 | * Do not set this until it has been set in the backend. |
| 129 | * This is used for generating expiring pre-authenticated URLs. |
| 130 | * Only use this when using rgw and to work around |
