I think this is what you're looking for: (https?:\/\/(.+?\.)?example\.com(\/[A-Za-z0-9\-\._~:\/\?#\[\]@!$&'\(\)\*\+,;\=]*)?).

It breaks down as follows:

• https?:\/\/ to match http:// or https:// (you didn't mention https, but it seemed like a good idea).
• (.+?\.)? to match anything before the first dot (I made it optional so that, for example, http://example.com/ would be found
• example\.com (example.com, of course);
• (\/[A-Za-z0-9\-\._~:\/\?#\[\]@!$&'\(\)\*\+,;\=]*)?): a slash followed by every acceptable character in a URL; I made this optional so that http://example.com (without the final slash) would be found.
