You can't tell whether or not a page uses SSI before parsing it, and parsing
happens after the server has sent the HTTP headers.

Wildebeest is configure to process all .html and .shtml pages with SSI. Changing
it to process only the .shtml extension is unfeasible, because we'd have to 
rename
a large number of pages across several repositories.

See also my comments in the Savannah ticket.

That's because the SSI command is not meant to be used for generating HTTP 
headers. It's usually expanded 
in the footer of pages.
