Dealing with url changes

[pallih]

I'm setting up a tracker for http://visir.is (a Icelandic news site).

I've noticed that when changes are done on headlines, their system makes new urls.

The urls are made up of these elements:

http://visir.is/g/<ARTICLE_ID>/< HEADLINE >

To view the article the < HEADLINE > part is reduntant.

To get around it I made some changes to allow for a regex to be applied to a url from the rss feed. See here:

pallih@0519f31

This makes the url checked: http://visir.is/g/<ARTICLE_ID> so subsequent changes to the headline are picked up, and not stored as a new article.

I'm not sure introducing a config variable is appropriate for the project, but at least my solution is there, if anyone needs it.
