I'm pretty sure that the request is being made authenticated. Reasons for thinking so include:
1. I'm passing the correct authentication credentials to the Net::Twitter object. 2. Dumping the data structure corresponding to the Perl libwww user agent shows an 'authentication' structure containing those credentials; this should mean that those are the credentials that libwww will send to Twitter. 3. While the 'user_timeline' method returns 404 whatever I send it, if I switch to using the 'friends_timeline' method, I will get either a '200' or a '401' response, depending on whether I pass in a correct username/password combination or not. The 'following_timeline' method (which wraps a call to '/statuses/ friends_timeline' in the Twitter API) and the 'user_timeline' method (which wraps a call to '/statuses/user_timeline') are line-by-line identical except for the URL, so I'd expect them to behave the same way in the case of an authentication failure. Are there any headers or arguments that are mandatory for 'user_timeline' that are not required for other, similar API functions?
