[webkit-dev] How does Safari identify form fields for auto-fill?

[Trey Matteson]

The short story is it uses a bucket-load of heuristics, since there  
is no reliable way to do it.  The login form is a special case of a  
"general" form that Safari might autofill.  From memory, I believe  
those are identified as forms with exactly two text fields, one of  
them a password field.  If there is a third field (e.g., "domain" in  
an NTLM setup), Safari punts, because it doesn't have a way to store  
arbitrary fields of into in the key chain entry.  Also popups that  
are part of such a form are not handled.  I also remember that a form  
with autocomplete=off will be skipped (which I always thought was a  
big lose for users).
