Thank you so much Eliezer for the quick response. I am so happy to see
such a detailed response here which I could not get in any forums.
Please find my replies and a few queries inline.

Vinay: It can test Basic, Digest, NTML and Kerberos. I want ensure
that my client working can work with just not through Squid but any
other enterprises level proxies in the world.
I am not in IT domain but a QE engineer and want to ensure I can have
a best possible coverage for my client. I agree that Squid is one of
the best avaiable proxy server but my job is to ensure that my client
works with other proxies too.

Vinay:
I tested that the client can establish the connection through Squid
but before testing in rest of the proxies in world. I want to know
that does it even make sense to do this exercise. Can I assume that if
my client can establish the connection through squid, it will be
capable of establishing connection through any other proxies in the
world?

Vinay: I am not comparing the development team around the world but
trying to get some statistics around the widely used proxy server so
as to ensure my test coverage is maximum.
