When running integration cycles with CruiseControl.NET there are commits when CCnet need not trigger. That's the case when you have documentation folder or anything similar in your project path.
There is a nice way to tell CCnet to ignore files and folders. Instead of using any of the regular Source Control Blocks, for example Subversion Source Control Block, you should use Filtered Source Control Block then copy/paste your old source control block inside and rename it to "sourcecontrolprovider". At last list some exclusions and you're all set.
Let's see this by simple "before and after" screenshot:
Although filter by path is probably most used, there is also option to filter by source control user or action.
