## Discussion

HTTP Proxy property. To cause an HTTP CFStream to use an HTTP proxy, set the value of this property to a CFDictionary that includes at least one host/port pair described in “CFStream SOCKS Proxy Key Constants” in <doc://com.apple.documentation/documentation/CoreFoundation/cfstream>. SystemConfiguration returns a CFDictionary that is usable without modification.
