BotDetect.ValidationAttemptOrigin

Enumerates all BotDetect Captcha validation attempt origins. Different origins can result in different validation rules being applied.

BotDetect.ValidationAttemptOrigin Enumeration Members
	Unknown	The validation origin isn't set
	Server	The validation attempt is a result of server-side code called from a full postback
	Client	The validation attempt is a result of server-side code called from an Ajax call

BotDetect.ImageFormat

Enumerates all BotDetect Captcha image output formats.

BotDetect.ImageFormat Enumeration Members
	Jpeg	Captcha images will be converted to the JPEG image format. Results in good image quality and reasonable image sizes; used by default
	Gif	Captcha images will be converted to the GIF image format. Only suitable for some image styles, resulting in lower image quality with the more color dynamic image styles
	Png	Captcha images will be converted to the PNG image format. Results in good image quality and image size, but not supported in older versions of Internet Explorer (would be used by default if this wasn't the case)

BotDetect.SoundFormat

Enumerates all BotDetect Captcha sound output formats.

BotDetect.SoundFormat Enumeration Members
	WavPcm16bit8kHzMono	The default format, used for underlying Captcha sound generation. Reasonable sound quality for Captcha purposes, resulting in moderate sound file sizes. Supported by most clients
	WavPcm8bit8kHzMono	Lower quality Wav format option, resulting in smaller sound file downloads while retaining good enough quality in most cases

BotDetect.SoundRegenerationMode

Enumerates all BotDetect Captcha sound regeneration modes.

BotDetect.SoundRegenerationMode Enumeration Members
	None	Generate only one sound response per Captcha code, cache it on the server, and serve it for all consecutive sound requests.
	Limited	Allow generation of a limited number of different sound responses (the minimum required to make Captcha audio work in all supported client browsers and devices), and automatically change the Captcha code on the client for consecutive sound requests if needed and possible.
	Unlimited	Each audio request will generate a new Captcha sound response (previous BotDetect version behavior).

BotDetect.Status

Tri-state logic switch, used when detecting a condition might fail and leave the result undetermined. For example, the SessionTroubleshooting helper will attempt to detect is the ASP.NET Session state HttpModule running, but might fail with stricter server permission settings (in Medium Trust). Since we want to be able to tell whether the detection failed or the module was really not running, we use a BotDetect.Status return value.

BotDetect.Status Enumeration Reference
	Unknown	The logical condition could not be tested
	False	The logical condition was successfully tested, and evaluated as not satisfied
	True	The logical condition was successfully tested, and evaluated as satisfied
