Customization You can use various methods to make the IPL T SFI244 interface perform customized functions or to alter the unit’s embedded Web pages. Server Side Includes (SSIs) make it possible to send commands to the IPL T SFI244 itself, or to devices connected to its control ports. Customization is also possible by writing query strings and inserting them into Web pages stored on the IPL T SFI244.
-
See the following examples of the basic SSI command format. Server Side Include for a Host SIS command Quotation marks are delimiters. SIS command to be executed by the IPL T SFI244 (must be typed without spaces) Examples: Request unit’s part number. Request system memory usage. W is the Web-encoded substitute for the E key. View date and time. Figure 35.
-
Query string command types and syntax As with SSI formatted commands, query strings can use any valid SIS command of either type (host or remote). • Host commands instruct the IPL T SFI244, itself, to act or respond. • Remote commands send data to an external control port on the IPL T SFI244. The basic format for a query string with a link is as follows: linked text where x is the SIS command to be executed. Text between the quotation marks is typed with no spaces.
-
Code Examples This section shows practical uses for both SSIs and query strings. NOTE: Before attempting to develop new Web pages, the user should have a good, working knowledge of JavaScript™, HTML, and Server Side Includes. Example 1 In figure 40, both host SSI and remote SSI commands are used within the same Web page. You will notice six SSIs: three host commands and three remote commands.
-
