bill, you can find info on the intercepting filter @ http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnpatterns/html/DesInterceptingFilter.asp
the main difference between an intercepting filter and CoR is that in CoR the request is handled by one candidate while in intercepting filter the request is potentially modified by each filter. an example: in a web service engine built around the intercepting filter pattern, one filter can remove ssl, another can process http headers, another can processthe content, another can return a response, another can wrap the response back in ssl intercepting filters provide more pluggability and work on the principle that the pre-condition for one == post-condition for the previous one. i've used COR and IF for xml doc parsing, both have benefits / risks. -saad --- Bill Bassler <[EMAIL PROTECTED]> wrote: > From my perspective, I think you're right on the > mark.
