We are currently using "rescue_action_in_public" in application.rb to catch exceptions and send us alert emails. However, we have recently begun getting thousands of invalid requests with weird and very long URLS. My guess is that it is Windows viruses that the user isn't even aware of since they are mainly coming from Windows machines and lots of different IP addresses. Our problem is the at it's clogging up our log files and I think these are innocent (but annoying) enough to ignore.
What's the cleanest way to detect an invalid exception based on the URL and not have it logged?
Not a direct answer to your question, but you may consider switching your setup to use hoptoad and then if they haven't already integrated my patch to ignore certain user agents, patch it do to so. Or just look at my patch and adjust it to fit your scenario.
