Re: username and Password sent as clear text strings

[jfvanmeter () comcast net]

thank you Alvind, the web app is owned by a very large company not my client and that was one of the things my cleint 
could not comprehend is why the company did not hash the password in the first place.

Yes both the client and servers would need the IPSEC rule, my client is a Windows shop, so they could leverage group 
policy to push out the IPSEC settings to the environment.

Take Care and Have Fun --John
