WebResource.axd not found for HEAD requests

[Håkan]

I have a problem with exceptions beeing thrown when I recive HEAD requests
for Path '/WebResource.axd'

For some reason some web browsers out there do HEAD requests when accessing
WebResource.axd.

When I check in the IIS configuration .axd-files are maped for both GET and
HEADrequests ( and some others as well) but when I look in web.config in
the config folder for asp.net the WebResource.axd file is only maped for GET
requests. Is this correct? is there any way of avoiding these exceptions?
