A blacklisted URL is a URL that the JumpSeat console will NOT display on.
When an application is added to JumpSeat, a URL can be added in the details. This enables the JumpSeat console for all URLs beneath that URL i.e., http://example.com and will display JumpSeat when visiting http://example.com/page, http://example.com/page/section and so on.
By blacklisting URLs, JumpSeat will no longer load or display the console on those specific blacklisted pages. This can be useful for popup windows, login pages, and any other pages deemed necessary.
