Speed Up Browsing
When you connect to a web site your computer sends information back and forth.  Some of this information deals with resolving the site name to an IP address, the stuff that TCP/IP really deals with, not words.  This is DNS information and is used so that you will not need to ask for the site location each and every time you visit the site.  Although Windows XP and Windows XP have a pretty efficient DNS cache, you can increase its overall performance by increasing its size.

You can do this with the registry entries below:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters]
"CacheHashTableBucketSize"=dword:00000001
"CacheHashTableSize"=dword:00000180
"MaxCacheEntryTtlLimit"=dword:0000fa00
"MaxSOACacheEntryTtlLimit"=dword:0000012d

Make a new text file and rename it to dnscache.reg.  Then copy and paste the above into it and save it.  Merge it into the registry.

Proxy Servers

 

Most home and small office networks use a dial-up or modem network connection to an ISP, which in turn connects them to the Internet. The ISP assigns a single IP address to each network for connecting to the Internet. In addition, each computer in a network requires an IP address for Internet connection. Rather than using separate IP addresses for each computer, it is more cost-effective to use a single IP address for multiple computers. A proxy server is a firewall component that enables you to connect multiple computers in a network to the Internet by using a single IP address. Proxy servers have two main functions: to improve network performance and filter client requests.

 

  • Improve performance

Proxy servers reduce the time it takes to respond to requests made by groups of users. This is because a proxy server caches, or saves, the results of all requests made during an interval of time. If a user wants to redisplay a Web page that was requested earlier, the proxy server simply returns that page to the user rather than forwarding the request to the Web server and downloading the page again.

 

  • Filter client requests

Proxy servers can also be used to filter client requests for certain Internet connections. For example, a company can use a proxy server to prevent its employees from accessing a specific set of Web sites.

 

How Does a Proxy Server Work?

When using a proxy server, the computers on the local network are configured for private IP addresses. When a computer makes a request to connect to the Internet, the computer passes its data through the TCP/IP network to the proxy server. The proxy server modifies the request, inserts its own name and IP address, which was provided by the ISP, and sends the data out on the Internet. When a response to the request is received, the proxy server passes it back through the local network to the computer that initiated the request.
