[silva-dev] Breaking Code Elements cached

Hi

this is a issue with Silva 1.1, and I'm not shure if this was fixed in
the mean time:

If a code element fails, the page will be displayed with a message like
this instead of the desired output:

  [external source element is broken]
  error message: content

The error gets trapped completely by Silva.

The problem: this page will be delivered like every other correct page.
After all it will be *cached* in HTTP caches like every other correct page.

Even if the error is fixed, clients will still see the error because
they rely on the cached page, as long as their copy is not expired.

Therefore Silva must indicate that this page could not be assembled as
desired. I suggest that the Code Element class sets the reponse header
to 400 (Bad Request), this will avoid any HTTP caching.

Regards

Bengt
