There are different ways for doing this. The simplest is to generate the image yourself, and you can use a pseudo-caching method to pull them statically if they are not already generated. This method can still be automated, but it is at least more difficult than writing a simple script, as it requires some OCR. If you want to go the extra mile, check out this site: http://www.captcha.net/ gimpy-r is what Yahoo! uses for their registration. These images are extremely difficult to reliably read with a computer program, so they offer much stronger protection against automated attacks. If you specifically want to know what TicketMaster/CitySearch uses, you should ask on the mod_perl mailing list, because a few of those guys work there. Hope that helps.
