I am trying to add some ajax functionality to a public facing site and have added a custom web service both into the layouts fodler and also into _vti_bin.
I can browse to the asmx file OK however am getting a 403 error when trying to call the service via Ajax.
Anonymous browsing is on for the site.
Am I missing something out to get it to work anonymously
On a side note I found when I browse to the asmx file in the layout folder the 'Invoke' button is available however when I browse to the asmx file in the _vti_bin folder it is not visible. Not sure if this is related
