WebKit itself does not have error pages. This is a feature of specific browsers: Recent versions of Safari do this, although earlier versions used sheets and alerts instead.
I think it’s reasonable to have a way in DumpRenderTree to indicate somehow in its output if a page load fails and what error code is involved. But I would not recommend using "error pages" as the way to do this. And we’d have to be careful to make this something easy to use cross-platform. Specific error codes are also likely to be platform-specific.
There may be some way to accomplish this in some cases using "onerror" and frames.
We’ve welcomed patches many times in the past that add things to DumpRenderTree that help us test previously untested aspects of the engine.
