Coldfusion 8 & Twitter - cffeed unable to read the source URL. Status Code: 400

Question

In Coldfusion 8 Enterprise (8,0,1,195765), the following two lines of code causes this error:

Unable to read the source URL. Status Code: 400 Try adding or changing UserAgent attribute in the CFFeed tag

<cffeed source="http://twitter.com/statuses/user_timeline/62944327.rss" query="twitter">
<cfdump var="#twitter#">

Yet, on my development box with Coldfusion 8 Standard (8,0,0,176276), it's working.... Argh. Any ideas why?

Answer 1

Does the server running Enterprise have to go through a proxy to get out? I've had that happen before with cfhttp, it works on dev but not in production because the production box goes out through a proxy and you have to supply the proxy info to make it work.

Answer 2

Not sure, but possibly it is caused by rate limiting as explained on this page
