Chapter 3 Managing Websites 37

Changing the Access Port for a Website

By default, the server uses port 80 for connections to websites on your server. You may

need to change the port used for an individual website, for instance, if you want to set

up a streaming server on port 80. Make sure that the number you choose does not

conflict with ports already being used on the server (for FTP, Apple File Service, SMTP,

and others). If you change the port number for a website you must change all URLs

that point to the web server to include the new port number you choose.

Note: If you turn SSL on for a site, the port for that site is automatically changed to 443.

If you turn SSL off, the port will change to 80, regardless of what it was previously. A

message on the screen alerts you to the port change when you turn off SSL.

To set the port for a website:

1 In Server Admin, click Web in the list for the server you want.

2 Click Settings in the button bar.

3 In the Sites pane, double-click the site in the list.

4 In the General pane, type the port number in the Port field.

5 Click Save.

Improving Performance of Static Websites

(Performance Cache)

If your websites contain static files (such as images), and you expect high usage of the

pages, you can enable the performance cache to improve server performance. For

example, for a site that has static images that are displayed on dynamically generated

pages, a good way to use the performance cache is to store all images on a separate

virtual host that has the performance cache turned on, while the generated pages

come from the main virtual host.

The performance cache is enabled by default.

You should disable the performance cache if:

• You do not anticipate heavy usage of your website.

• Most of the pages on your website are generated dynamically.

Understanding the Effect of Using a Web Service

Performance Cache

Web service’s performance cache is enabled by default and significantly improves

performance for some websites. Sites that benefit most from the performance cache

contain mostly static content and can fit entirely in RAM. Website content is cached in

system RAM and is accessed very quickly in response to client requests.
