The app I was writing when this came up should display a similar enough message between a 204 or network failure. But realistically, how often is that going to happen? You're already browsing to the site when you load the JS. The JS should hit the same domain asking for an Ajax response so unless your connection drops between downloading the JS and the Ajax request that shouldn't ever happen. Or, at least it seems that way. Probably assuming too much on my part though. @Sergiu – True, although in my case that doesn’t really matter.

If they had just made it work with the standard response codes none of this would work. Fortunately the Prototype authors let the on### functions work for any number.

I ran into the same problem for which there is no alternative accept to use a different, less "spec", status. In the HTTP 1.1 spec it says of the <b>204 No Content</b> status code: <i>"…The response MAY include new or updated meta information in the form of entity-headers, which if present SHOULD be associated with the requested variant."</i></blockquote> Yet, the accompanying header information for this status is not available to either IE (as of v 7.x) or Opera (as of v 9.6) via the XMLHTTPRequest object.
