Thanks for the response and suggestions, I got it by setting the edit-link-type to webdav.
Has anyone found out how to Configure Webdav editing in Firefox,yet?
You're welcome, but be aware that this solution works only for Internet Explorer.
Something similar could be implemented for Firefox by adding functionality to the
Firefox Add-on to open links of a particular class by passing the URL directly to an
external program, but this has not yet been done.
