The crawl start provides fields for regular expressions to include or exclude urls.
Then there is the crawl scheduler where you can reschedule a crawl on a daily basis.

This is not a regex.

Maybe you should try http:\/\/example\.com\/.+\/abc.+\.html
I by myself am never sure which syntax to follow as regex are mixed sometimes (e.g. blacklist) with file globs (stuff with *)
