I'm affraid it's related to this bug whic is fixed in 6.0 http://issues.umbraco.org/issue/U4-1411 . I don't think it's fixed in the 4.x codebase also.  Maybe you can re-open the issue for the 4,x codebase?

Cheers,

thank you for confirmation of this behaviour. I thought it might have been caused by a non-perfect upgrade to the newest version of U4.

I have created a work-around for this behaviour, which works with manually entered redirects, as well as with automatically created redirects caused by a node rename.

Solution:

-- ================================================
-- Insert Trigger for infocaster301
--
-- This trigger fixes Umbraco behavior of 
-- version 4.10 and newer - where file extensions
-- are stripped from the request, also .aspx
--
-- For every .aspx link, another link without 
-- .aspx extension is generated
-- ================================================
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
