Then why are you claiming you've done _anything_. There is literally _nothing_ new here - you're telling me stateful web apps are your invention?
This whole thread is based on a misunderstanding. G-WAN does not have any CAPTCHA support. The example merely demonstrates how to use G-WAN's image generation API.
The CAPTCHA example is not meant to be used without modification in an application. CAPTCHAs are not a feature of G-WAN.
No where did anyone claim to have invented stateful web applications.
