It may also start several other sub-processes for tasks such as DNS lookups or client authentication, but all the actual HTTP protocol processing is done in the single master process. This might make sense if you want to give only certain people access to the web, and cannot use IP address validation due to the use of dynamically assigned addresses on your network. Because being able to view web pages is extremely useful, a proxy is often set up so that websites can be accessed through it.

Take a look in the access. All browsers and programs that can make use of a proxy also support proxy authentication.
Every time a cacheable page is requested it is stored in a file, so that when a subsequent request for the same page arrives the file can be read and the data served from it. You can apply this same idea to nearly anything you’d like to block.
If you’ve installed from a vendor supplied package, Squd will probably already know where to find everything. You can add to and edit entries in the ICP restrictions table in exactly the same way as you would for proxy restrictions. Views Read View source View history. Delivered Wednesdays and Fridays.
Squid Proxy Server
Once you have created some ACLs, they can be put into use by creating, editing and moving around proxy restrictions. Other programs such as wget or rpm require the username and password to be specified on the command line. A user can be edited by clicking on its name in the proxy users list, changing the username, password, or enabled status, and hitting the Save button. As soon as a restriction is found that matches the ACLs for the request, its action determines whether the request is allowed or denied.
The table below lists those that you can create for Squid 2. Then, based on the ACLs that each request matches you can choose to block it, prevent caching, force it into a delay pool, or hand it off to another proxy server.
If Squid fills up your entire hard drive, problems may occur because other programs are unable to create temporary files or write to logs. This is most useful for keeping usernames and passwords in sync without needing to grant access to every single UNIX user.

If you want to set up or configure Squid from within Webmin, you will need to use the Squid Wbmin Server module, found under the Servers category.
Thanks to Webminthat is not the case.
If your program validates users against some other database or server, or if the module cannot figure out which file contains webjin from the command, the Proxy Authentication icon will not appear.
Squid can be compiled on all the flavors of Unix that Webmin supports, and works configguracion identically on all of them. This can be done by specifying multiple directories, each with its own maximum size. Once an ACL has been created you can edit it by clicking on its name in the list, changing squdi fields and clicking Save. It is open source and is freely available for download from www.
