Passing correct url but method still returns false… Any idea?

Question

I verified url (http://portal.inhouse.dev/sites/promo/libray1/test.txt) but following method always returns false. It should return true per MS. Please suggest. I even tried it with http://archive.msdn.microsoft.com/webservicestudio20 and still returns false and nulls for output fields.

public static string GetListItemIDByUrl(string url)
{
    sitedataservice.SiteData sd = new sitedataservice.SiteData();
    sd.Url = "http://basesmcdev2/sites/tester1/_vti_bin/sitedata.asmx";
    sd.UseDefaultCredentials = true;

    string webId = string.Empty;
    string listId = string.Empty;
    string itemId = string.Empty;
    string bucketId = string.Empty;

    bool ret = sd.GetURLSegments(url, out webId, out bucketId, out listId, out itemId);

    return itemId;
}

Answer 1

As I understand this post, you retrieves FALSE value because the item is located in the _vti_bin bin directory. This is virtual directory, not a list.

Answer 2

Context.

Your web service call has context of the web "tester1" but you're looking for a file in the web "promo". The web service can only get files for the web in which it currently has context.
