I am using abort and redirect_to imported from pylons, I do not use
HTTPExceptions directly (neither webob nor paste).
I've added a print to WSGIController it shows exception of type
webob.exc.HTTPNotFound.
(line 109)
try:
result = self._perform_call(func, args)
except HTTPException, httpe:
...
result._exception = True
So it seems that the exception gets intercepted correctly. There is probably
something wrong down the pipeline. StatusCodeRedirects?
Again, here is full sequence.
My code calls abort(404). Browser shows:
File "/home/max/projects/site-baseline/doupy/doupy/lib/base.py", line
215, in __call__
redirect_permanently(url)
File "/home/max/projects/site-baseline/doupy/doupy/lib/base.py",
line 47, in redirect_permanently
redirect(url, code=301) # Moved permanently

raise exc(location=url).exception
HTTPMovedPermanently: 301 Moved Permanently
Content-Type: text/html; charset=UTF-8
Content-Length: 0
location: http://127.0.0.1:5010/error/document/
It seems to go as following: the HTTPNotFound gets intercepted,
StatusCodeRedirects creates "internal redirect" to /error/document/ but
forwarding to this url fails for some reason. I have turned on DEBUG
logging, here is what happens:

If I simply open http://127.0.0.1:5010/error/document/ it opens as expected.
So routing to this url works.
What's wrong???
