Modifying Web server Internet port and protocol settings

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.
  3. Click the Internet Protocols > HTTP tab, and change any of these fields:
    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.
  4. Also on the Internet Protocols > HTTP tab, make changes to any of these fields:
    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.
  5. Save and close the document.
  6. Enter this command at the console so that the changes take effect:

    tell http restart
