▪When referencing a SQL Server named instance, use + to separate the machine name and instance name. For example, if the SQL Server instance is named \\MyLocalMachine\MySQLServer then the correct URL is http://localhost:8889/SARest/SQL/MyLocalMachine+MySQLServer

▪When referencing a type name in URLs, special characters such as spaces or question marks must be encoded. The table below lists the mapping between a special character and its corresponding replacement character in the URL.
