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 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? >> Query3: Is there any usage data at enterprise level that what are the >> top 5 widely used proxy servers? > > Lets clear one thing: > - IBM still uses squid 2.7 in couple of their products.. > - SUSE provides squid for enterprises. > - There are easiest ways to make things work with enterprise authentication > then to configure and use squid. > - All proxy servers like BlueCoat, TMG, maybe F5 and others do their work > for their clients best interests... > > You cannot in any way compare a development teams of hundreds to a > bunch!!!(hint: http://wiki.squid-cache.org/WhoWeAre) > 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. > I do think that squid is a very good proxy but some environments require for > the sysadmin or netadmin to not take things(testing, debugging) on > themselves and use the power of another company or human resources which > will give them a piece of mind to sleep at night.(even if it's not 100% > true) > > This is from me that many people do think of me as unique. > I can tell you that my knowledge cannot be compared to others which are > greater then me(in so many ways that this is not the place to write about). > Also every time that I get stuck on something I know that without the others > who helps me to think and relax I could not stand for a week on my feet. > > Also this is why I like to help others: Because they need it as much as I! > Vinay: Even I do think that you are unique and appreciate your effort to help the community. > All The Bests, > Eliezer > > P.S.
