New Post: How to convert indirect URL to direct one.

I use a filteredstream with a number of filters. When a tweet event fires, I need to deduce which filter the tweet relates to, as this affects what I do with the information.

This is fine, except in some cases the filter has been matched not on the text in the tweet, but on a URL which is embedded in the tweet, unfortunately the URL presented in the tweet is an indirect shortened one which contains no trace of the original filter. For example, using a filter of the word 'golden' I receive this tweet:

[Raspians (@Raspians) posted] RT @TheRascalPower: @Raspians https://t.co/nZLJdBm9bI help us be the change! #BeTheChange #charity #india #charitywater #Travel #WeNeedYo…

No mention of the word 'golden' in there. But if browse to the short URL it redirects to
https://www.indiegogo.com/projects/documenting-change-the-golden-triangle#team&ui-state=dialog

which does contain the word 'golden'.

Is there any way I can get the hold of the original URLs from the Tweet object?

Thanks.
