When the user agent requests a page from the web server, and the page designates a Server Response File (that is, the file
is in a directory associated with BIS and has a .srf suffix), the page is automatically served by the BIS Request Handler. The page is processed from top to bottom and tags are
rendered as they are encountered.
There are two basic kinds of rendering tags:
- Processing Control Tags are tags that are completely removed from the final rendered content.
- Substitution Tags are completely replaced in the final content by new (possibly empty) text.
If a tag is not recognized, it is rendered literally-that is, the tag appears in the output unchanged.
Note: Tags are order-dependent. A particular tag may affect how subsequent tags are rendered; for example, the StartService tag specifies the service that the XMLExchange tag uses. In addition, the Handler tag must be the first non-comment tag in every file, and it must appear within the first 4096 characters of the file.
