MarkLogic 12 EA 1 Product Documentationxdmp.setSessionField
xdmp.setSessionField( name as String, value as Sequence ) as Sequence
Summary
Sets the value of a named session field for the session created
by the
xdmp.login function.
| Parameters | |
|---|---|
| name | The name of the session field. |
| value | The value of the session field. If you pass in a single value, it is treated as a Sequence with that single item; therefore, if you pass in an array, the array is treated as a single value (not as one value for each item in the array). If you mean to pass in the values of each item in the array, then you can call xdmp.arrayValues on the array. |

Usage Notes
You can use the
xdmp.getSessionFieldNames
function to return the names of the fields in the session and the
xdmp.getSessionField
function to return a value set in a session field.
If you set a session or server field to a value that comes from a
database node (for example, from the value of a search or the
fn.doc function),
then that session or server field expires
after the request time limit (10 minutes by default). These fields expire
because they contain references to stands in the database, and as long as
those references exist the stand cannot be reclaimed (merged). To keep
such a node in a session or server field, make a copy of the node
before adding it to the session or server field instead of using the node
directly from the database.
Example
xdmp.setSessionField("user", "marklogic");
=> "marklogic"
