-> I actually do a couple of things that let me reliably determine

-> request is authorized. The problem however is that there is a good reason
-> why the authorized webmasters would want to replace the links with forms
-> even if they are told not to.  Unless there is a way to check
-> whether they
-> use a link or a form they will get away with "breaking the rule" and will
-> keep doing it.  The only option I have left is to build a bot that would

-> link. Since
-> most of those sites are extranet sites protected by different types user
-> authentication I'll have to use a cURL based bot for
-> cookie/session support.
-> I'll have to require the webmasters to provide username/password
-> for the bot
-> to use when checking their site.
-> This is much more work than I expected.
