BUG: Registry Patterns Ignored for Pluggable Namespace Handlers

ID: Q190893

The information in this article applies to:

Microsoft Internet Explorer (Programming) versions 4.0, 4.01, 4.01 sp1, 5.0dp1, 5.0

SYMPTOMS

Internet Explorer 4.0 ignores the pattern keys set in the registry when determining which permanent pluggable namespace handlers to invoke.

RESOLUTION

Create a temporary pluggable namespace handler instead of a permanent namespace handler. Use IInternetSession::RegisterNameSpace and IInternetSession::UnregisterNameSpace to register and unregister a temporary pluggable namespace handler, respectively.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

Pluggable namespace handlers currently do not recognize the pattern strings set in the registry. This bug causes the namespace handler to be called for all protocol calls and not just the ones that match the listed patterns. As an example of what the correct behavior should be, a namespace handler entry in the registry as follows:


HKEY_CLASSES_ROOT\PROTOCOLS\Name-Space Handler\http\myserv-Handler
   CLSID = {..}
   Pattern1 = "myserver"

should only be called for URLs that begin with http://myserver/ and the default HTTP pluggable protocol handler should be called for all other HTTP URLs.
