You can add your own SSI aliases or, in other words, specify SSI file name extensions. For example, you can specify that all *.ssi files must be treated as server side includes.
To add an SSI alias, do the following:
- Select Domain info in the Domain Settings menu.
- Click the Edit icon in the Web Service field.
- On the Web Service page, scroll down to find the SSI option and click the Add icon on its right.
- Agree with the charges, if any.
In the window that appears, enter your SSI file extension beginning with a dot:
Skip this step if you are using a Windows-based plan.
At the top of the Web Service page, click the Apply link for the Server configuration to change. The changes will take effect within 15 minutes.
