Today I connect to my web-application using a Proxy server that supported SSL. I connected to my web-app (which is SSL secured HTTPS:// and I ented my User ID and Password, and used my WEB APP. Am I endanger of having my password stole because i used to the Proxy server? Does it retain the password, server / public key?

I thought of this and immediatly stopped using it. But now i am very concerned that the proxy server the person who owns it can use my password/user-id to log into my app. Is this true? and Should I be concerned.

Thanks :-/
