`static java.lang.String`	`LOGOUT_FIELD_NAME` Field name to be present to upload or login pages to force a logout.
`static int`	`MIN_UPLOAD_SPACE_BYTES` Minimum free space we will contemplate even attempting an upload at.
`static java.lang.String`	`PASSWD_FIELD_NAME` Form field name for user password.
`static java.lang.String`	`searchWindow` Hopefully-unique (but constant between runs) window name to place search page in.

Field Detail

searchWindow

public static final java.lang.String searchWindow

Hopefully-unique (but constant between runs) window name to place search page in.

See Also:: Constant Field Values

USERID_FIELD_NAME

public static final java.lang.String USERID_FIELD_NAME

Attribute (and form field) name under which we store (verified) contributor ID (initials). Prefix with "X-" to use as an HTTP header.

See Also:: Constant Field Values

PASSWD_FIELD_NAME

public static final java.lang.String PASSWD_FIELD_NAME

Form field name for user password. Prefix with "X-" to use as an HTTP header.

See Also:: Constant Field Values

attrUIB

public static final java.lang.String attrUIB

Attribute name under which we store UploadInfoBean.

See Also:: Constant Field Values

exhibitFile

public static final java.lang.String exhibitFile

Name of parameter containing exhibit file for upload.

See Also:: Constant Field Values

LOGOUT_FIELD_NAME

public static final java.lang.String LOGOUT_FIELD_NAME

Field name to be present to upload or login pages to force a logout.

See Also:: Constant Field Values

LOGGED_IN_HEADER

public static final java.lang.String LOGGED_IN_HEADER

Header name on login page to indicate user is logged in. Must start with "X-" to avoid breaking any other code.

See Also:: Constant Field Values

LOGIN_URL

public static final java.lang.String LOGIN_URL

See Also:: Constant Field Values

MIN_UPLOAD_SPACE_BYTES

public static final int MIN_UPLOAD_SPACE_BYTES

Minimum free space we will contemplate even attempting an upload at. Note that this had probably better be at least a couple of blocks, to represent filesystem consumption for directory and file data, and anyway tiny uploads are not likely to be much use!

See Also:: Constant Field Values

BATCH_UPLOADS_CAN_BE_PIPELINED

public static final boolean BATCH_UPLOADS_CAN_BE_PIPELINED

If true, then we can pipeline multiple batch uploads in one POST to the non-browser upload servlet.

See Also:: Constant Field Values

BATCH_UPLOAD_MAX_IDLE_MS

public static final int BATCH_UPLOAD_MAX_IDLE_MS

Maximum time uploader connection should stay idle before being shut, ms; strictly positive. As connections for batch uploads are non-interactive this need only be long enough to allow for:

Glitches in connectivity and TCP/IP data flow.
Client and server turnaround time moving to the next upload.

This period applies while no upload is in progress; a somewhat longer timeout should apply during upload to avoid glitches forcing an upload to be started again later.

A few tens of seconds should suffice, and help free unused resources quickly.
