Hello all, When I call _method= DELETE in List API, I got 401 Unauthorized from api.twitter.com. After I read the document of OAuth, it mention that "_" is no need to encode so it may be a another problem. I have try when I using other parameter include "_" like "a_method=DELETE" is work well and return 200 OK, So, I wound it is the problem in server side?? I can't develop in my twitter Client using Flex in FireFox more since this problem ,can any twitter support team member help me to find out what is the problem?? or any people can success use _method as parameter in Oauth can provide solution for me?? Thanks.
