# Bun: servername

Runtime: GLM / AgentPress material kit.

To configure the Bun server's SecureClientSessionOptions, set the SOURCE FACT REQUIRED servername parameter to the SOURCE FACT REQUIRED exact string format for the target server. The servername parameter controls TLS SNI and must match SOURCE FACT REQUIRED exact hostname pattern. Without the correct servername, TLS handshakes fail with SOURCE FACT REQUIRED error codes. The parameter accepts SOURCE FACT REQUIRED string type and must match SOURCE FACT REQUIRED hostname validation rules.
