Using my android device I went to "mail.yahoo.com" on my web browser. It forwarded me to this page: http://mlogin.yahoo.com/w/login/user ...
The page prompts me to enter my username and password, but the page is not HTTPS! I examined the source and it looks like the form action posts to "https://mlogin.yahoo.com/w/login/auth?.ts=1341545330&.intl=PR&.lang=es-pr".
My question is how safe is that? It seems very risky to enter your username password on a page that isn't secure.
Another question is do web browsers allow the opposite: a secure webpage that ends up submitting the form to an unsecure page? If so that seems very bad security policy on behalf of web browser makers.
