AddUserHeader is a position-dependent config.txt directive that interacts with database definitions. AddUserHeader directs EZproxy to include a header containing the current user's username when proxying to a database.
-base64 is an optional qualifier to indicate that the username should be encoded in base 64. headername specifies the name of the header that should be used when sending the username. Omit both -base64 and headername to direct EZproxy not to include this header for the databases that follow.
AddUserHeader -base64 headername
This directive is position dependent, allowing its use to vary by database. In the following example, Some Database receives the X-User header, Other Database and Another Database receive the X-Username header with base64 encoding, and Yet Another Database and databases that follow it do not receive any header at all.
