We support SSI. What is SSI?
SSI, or server-side include, refers to Perl-based HTML commands that direct a server to generate on-the-fly content for web pages. Pages with SSI commands frequently end in .shtml. Most UNIX-based web hosts are likely to support SSI.
SSI is commonly used for such functions as generating current dates and times, including content from other source files in a web page, and displaying a web page's last modification date.
