Port 8090


HTTP Alternate Alternate (see port 8080 and port 81)

This port is a somewhat less popular alternative to port 80 for offering web services. (The more popular alternate port is 8080.) Like 8080, its use in a URL requires an explicit "default port override" to request a web browser to connect to port 8080 rather than the http default of port 80. See the discussion of URL defaults and port overrides on the port 81 page.

Related Ports: 
80, 81, 82, 443, 8080

Background and Additional Information:

For information about the use of services about the 1023 lower-port limit, see the discussion on the port 8080 page.

For further information regarding accessing alternative ports, see the discussion on the port 81 page regarding URL defaults and overriding the default ports used by Internet protocols.
