    Thanks for your reply.

    I don’t see any way to send you a private message, would you be interested in setting up what I asked about?

  2. Shawn says:

    Thank you the response.

    A couple more questions if you don’t mind:

    Can I set up a SOCKS proxy on the server, using an extra IP provided by the hosting provider. And, if so, can the IP used for the SOCKS proxy also be used as a normal extra IP address, if that makes sense. I’m hoping to be able to use the IP to log in to a different website that my site logs into on behalf of users of my site, and also use it as for the SOCKS proxy. The idea is to let users of my site configure their browser to use the SOCKS proxy so they can then go to the other site and log into it manually, so that the other site sees the SOCKS IP as safe for that user’s log in attempts in the future, by my site.

    Again, thanks for your reply to my last post to any reply to this one.

      Yes, as I said in my last comment you can setup SOCKS proxy with extra IP address and also you can use that extra IP for other things too..

    Maybe a stupid question, but can Squid be set up on a vps server that already has websites installed on it? I need a socks proxy for use with the website already installed on the server?

    A reply would be greatly appreciated.


    • Ravi Saive says:


      Yes you can setup Proxy on running Apache/Nginx web server with websites, there isn’t any problem using..

  4. Very nice article, it was really helpful for me! Thank you!

    I want a HTML based page on squid proxy,so that they can monitor each user’s daily internet use with accessed sites & total download of the day of each user.Any open source is available?

  6. Medhansh says:


    Linux is case sensitive and in Q4 acl name should be same. I think there is some type mistake..

    Rest of the article is good and helpful for interview…

    Keep going…
