ISSUE-25: IIS and Access-Control-Policy-Path [Access Control]

http://www.w3.org/2005/06/tracker/waf/issues/

Raised by: Anne van Kesteren
On product: Access Control

IIS servers have an issue in that resources can be addressed by several distinct URIs as explained in this e-mail:

http://lists.w3.org/Archives/Public/public-appformats/2008May/0039.html

This impacts the design of Access-Control-Policy-Path to some extent. Two proposals have been put forward by members of the WG to address this issue:

A. If a URI (also one given during redirects, etc.) contains the "\.." sequence (or the escaped form) apply the generic network error steps.

B. Warn against using the Access-Control-Policy-Path feature in servers that exhibit this behavior.
