anyone know what that user agent is? and what it does? I was investigating my server's access logs and there's a lot of accesses from this user-agent. Problem is, I have a javascript validated form and I have been getting a lot of blank form submissions lately. I checked the time-stamp of the last blank form submission and it coincided with an access_log entry for that page by Java/1.6.0_03. Does anyone know if this user-agent has been known to do this? And if yes, then how do I block access for this user-agent?
That looks like the generic user-agent you get when you use the built in Java classes for accessing HTTP. So it's most probably a custom spam-bot written by the guy using it. User-agents are fairly easy to change and often used by both good and bad people so blocking access to a user-agent is usually a bad idea. I would probably add user-agent testing to whatever spam detection you have so that this user-agent's posts go to the moderation queue.
thanks for the reply ... I'm now doing both server-side validation in addition to client-side(javascript) validation, and I think its working. thanks again!
