A much more influential and resourceful preprocessing procedure is to use of SGML processor (such as the SP package) to produce your HTML, this can be self-validating. Examples of server-side inclusion are Server Side Includes (SSI, supported by Apache , NCSA , and other web servers), and Microsoft's Active Server Pages (ASP, supported by MS IIS). Processing transpires at the time the documents are essentially retrieved. A typical inclusion looks like
<!--#include virtual="/urlpath/to/myfile.htm" -->
