You should set the max age on the SSIFrame to 0
It will end up in the reply:
Cache-Control: max-age=0
And the browser won't cache it.

Well, it depends, some SSI should be cached for a long time, some other
not, it is up to you to decide on the cache time.
Note that an If-Modified-Since directive when present will be checked
against all segments, to be cache friendly :)
