Hi Mike and Jonathan,
Thanks for your prompt response.
Is there any corresponding API in Pyramid for the following?:
pylons.controllers.util.forward(wsgi_app)
Forward the request to a WSGI application. Returns its response.
return forward(FileApp('filename'))
Thanks,
Pinakee

all of that information is stored in the request object under:
request.registry.settings
Yes, request.registry.settings is equivalent to pylons.config. (At least in
the basic sense that settings parsed from "[app:main]" will be in this
dict.)

from pyramid.httpexceptions import *
from pyramid.httpexceptions import HTTPFound , HTTPNotFound

ons.html
you can read more about them here:
http://pyramid.readthedocs.org/en/latest/narr/views.html#http-exceptions
you can raise or return those objects from a view.
There's also a function that behaves closer to abort.
return pyramid.httpexceptions.exception_response(404)
they behave slightly differently when you `raise` than `return`.
IIRC, if you `return` you still have the request object in
subscribers, but if you `raise`, then pyramid's exeception handling
system takes control and you no longer have the request.
I thought Pyramid handled returning and raising HTTP exceptions identically.
Raising them does cut through intermediate stack frames (function calls) to
whichever level catches the exception, as with all exceptions. So that may
bypass subscribers. On the other hand, somebody who's asking these questions
is probably not using custom subscribers anyway.
