Vishal,
Best way to protect the proxy,MITM and DNS poisoning attacks is use of
One time tokens.
But they are also prone to Active MITM attacks.In order to achieve a
fool proof method better surrender yourself to cryptography(Zero
Knowledge proofs ) SRP(http://srp.stanford.edu/) based implementation
is a good start in which you dont effectively send the password.
This article will give some insights of how to protect the
webapplication from session
hijacking.(http://technicalinfo.net/papers/WebBasedSessionManagement.html)
Hope this Helps

Hi All,
Can someone please tell what is the most secure way of sending login
credentials to the server. The possible ways that I am familiar with are:
- get method
- post method
- hidden form fields
By using an encrypted connection we cannot sniff the credentials, but
still it is very easy to capture or manipulate these credentials
using a web proxy from any of these methods. So I am looking to find
a method to transport the credentials to the server so that the
security of these credentials can't be compromised even by deploying
a web proxy.
Also once a session id is generated, what is the best way to maintain
the security of a session id.
Any help would be much appreciated.
Regards
Vishal
