I had the good fortune to get paid to do some FlexWiki work this week. One
of my clients wanted CAPTCHA added to FlexWiki, and I was happy to oblige,
especially since they agreed to donate the code to FlexWiki. So I just
committed the change in revision 603. It should be present in build 2.0.0.42
and forward.
Here are the notes from the tracker submission:
CAPTCHA is implemented via the RequireCaptchaOnEdit, CaptchaKey, and
CaptchaLinkThreshold elements in flexwiki.config.
RequireCaptchaOnEdit has one of four values: Never, Always, IfAnonymous, and
WhenOverLinkThreshold. If "Never", CAPTCHA validation is never shown on the
edit page. If "Always", CAPTCHA is always shown on the edit page. If
"IfAnonymous", CAPTCHA is only shown in the user is no logged in. If
"WhenOverLinkThreshold", CAPTCHA is shown if a user tries to submit an edit
in which a certain number of links (http or https) have been added to the
page. The number comes from the value of WhenOverLinkThreshold.
CaptchaKey is the key used to encrypt the value of the CAPTCHA image to make
it harder to perform automated attacks against the system. It should be
changed from its default value to a random sixteen-digit hexadecimal number
by the site administrator.
