Allow upload of app_* directories through WebDAV

Hi!

We are using WebDAV to publish our ASP.NET applications to an IIS 6.0
server (W2k3). Everything works fine so far (including uploading aspx
files, after we discovered that "script source access" needs to be
activated), except for uploading App_* directories (App_Data,
App_LocalResources, App_GlobalResources, etc.) used by ASP.NET 2.0
applications (uploads to "bin" directories work fine, though).

I assume that the IIS ASP.NET 2.0 extension filters out access to
these "dangerous" directories, which makes it hard for us to deploy
our applications to this server. Is there some way to disable this
filter for the "WebDAV" web site? In IIS manager, neither the generic
"Websites" node nor our "WebDAV" web site show any ISAPI filters in
the corresponding property tab.

Greetings, thanks in advance,
Heinzi
