Hi,

I'm new to libcurl mailing-list. Just want to get some clarification.
I'm trying to upload a picture using libcurl to twitter, but twitter is
refusing with 'Could not authenticate you' message. The same Oauth
tokens works without any issues for other endpoints except
https://api.twitter.com/1.1/statuses/update_with_media.json.

I'm posting my request here in the hope of atleast confirming that my
request is correct according to OAuth rules. Here is my request,

Please someone help me to understand what is the problem with my
request? It would be much more helpful if someone point me to a working
implementation with libcurl for the above request.

Thanks in advance,
Mohan R
