- server-connector #!optional connectorparameter
This parameter holds a procedure which is invoked to establish a connection for an URI.
The procedure should accept two uri-common objects as arguments: the first indicates the URI for which the connection is to be made and the second indicates the proxy through which the connection should be made, or #f if a direct connection should be made to the first URI's host and port. It should return two values: an input port and an output port corresponding to the connection.
This can be used for nonstandard or complex connections, like for example connecting to UNIX domain sockets or for supplying SSL/TLS client certificates.
