This issue is caused in UrlRewriteModule.vb, on or about line 456.

In prior versions, the requested URI leaf would be compared against the glbDefaultPage value ("Default.aspx"); if the request was not for this page, then rewriting would terminate. In 5.4.2 this code read:

If Not Request.Url.LocalPath.ToLower.EndsWith(glbDefaultPage.ToLower) Then
' allows requests for aspx pages in custom folder locations to be processed
Exit Sub
Else
...
End If

This check is absent in the 5.6.1 version, presumably due to the fact that we want to perform some automatic mapping for requests that may not end in this value. Requests not processed by ASP.NET are, obviously, unaffected.

However, as the person herein noted, this is a breaking change for those applications that serve requests for pages outside of DNN; these include, in addition to ASPX pages, WCF services (SVC), and old-school services (ASMX).

This issue is magnified by the fact that the default behavior is to issue a 404 for such requests, which is confusing since the resources do in fact exist.

A workaround exists for installations that have some location flexibility; resources may be maintained anywhere in any of the { "admin", "controls", "desktopModules", "mobileModules", "premiumModules", "providers" } directories so long as the URI that precedes the directory is a valid alias.

Suggest allowing for a configurable list of extensions and/or paths that are omitted from rewriting; such a list should be extendable by hosts.
