You can change default Internet port and protocol settings for the Web server.

Procedure

1. Open the Server document that you want to edit.

2. Click the Ports -> Internet Ports -> Web tab and make changes to any of the following fields:

Table 1. Web (HTTP/HTTPS) fields

Field	Action
TCP/IP port number	Enter a port number. Default is 80.
TCP/IP port status	Choose one: Enabled -- To configure the server to listen for HTTP requests on the specified TCP/IP port. Disabled -- To prevent the server from listening for HTTP requests on the specified TCP/IP port. Redirect to SSL -- To redirect any HTTP requests that come into the TCP/IP port to the SSL port.
Enforce server access settings	Choose one: Yes -- To enforce server access settings for this protocol on the server. Server access settings are found on the Security tab of the Server document, and specify the names of authenticated users who have been granted access to this server, and those who have not. No -- To not enforce server access settings for this protocol.
SSL port number	Enter a port number. Default is 443.
SSL port status	Choose one: Enabled -- To configure the server to listen for HTTPS requests on the specified SSL port. Disabled -- If you do not want to use SSL for this server.

Table 2. Basics fields

Field	Action
Bind to host name	Choose one: Enabled -- To enter up to 32 IP addresses and/or DNS names in the Host name(s) field to which the Domino® server will bind. This allows users to access a Web server using a name other than the Domino server name. Disabled (default) -- To bind to all IP addresses on the server.
DNS lookup	Choose one: Enabled -- To have Domino look up the DNS name of the requesting client. The Domino log files and database contain host names corresponding to the machine used by the Web client. Disabled (default) -- To not look up the DNS name of the requesting client. The Domino log files and database contain IP addresses. Choosing Disabled improves the performance of the Domino server because the server does not use resources to perform the DNS name lookup. Note: The majority of browser users connect to the Internet through Internet server providers (ISPs), so the host names returned by DNS lookup are those of the ISP's proxy servers, not the individual user machines.
DNS lookup cache	Choose one: Enabled -- To have Domino cache the results of a DNS lookup for faster retrieval. Disabled -- To not have Domino cache DNS lookup results.
DNS lookup cache size	Specify the maximum size of the DNS lookup cache.Default value is 256.
DNS lookup cache found timeout	Specify the length of time, in seconds, that IP addresses remain in the cache. Default value is 120 seconds.
DNS lookup cache not found timeout	Specify the length of time, in seconds, between failed DNS lookups for a particular item. Default value is 240 seconds.

Table 3. Network Settings fields

Field	Action
Listen Queue Size	Specify the size of the operating system listen queue for incoming HTTP connections. Default is 512.
Maximum number of concurrent network sessions	Specify the maximum number of network connections the HTTP server will handle before refusing incoming connections. Default is 2000.

6. Enter this command at the console so that the changes take effect:
