Using the Proxy Server

A proxy server is a server which handles Internet connections on behalf of another computer. Proxy servers are usually associated with firewalls. Workstations on networks which are separated from the Internet by a firewall must use a proxy server outside the firewall to retrieve Web documents and other files and pass them through to the workstation.

A proxy server which caches documents retrieved from the outside can also serve as a performance enhancer even if the workstations it serves can directly access the outside Internet. This is the reason we have set one up here at Datasync.

Let's say you are using a browser to retrieve the Netscape home page at home.netscape.com. Your browser will first check its own cache on your computer to see if it has the page already. If not, it would have to connect to home.netscape.com in California to retrieve the page. However, if your browser is configured to use our proxy server, it will first ask the proxy server for that document. If it is in the proxy server's cache, quite likely in this case, the proxy server returns the document to your browser. You'll get it faster since your request never leaves Datasync's own network!

Documents that are frequently accessed by other Datasync customers using the proxy server will constantly be in the cache, resulting in much faster retrieval for you, especially when the remote server is busy. In addition, we experience much less traffic on our links to the Internet, making everything work that much faster. In fact, you'll be doing your part to lessen traffic on the entire Internet.

Highly interactive sites such as Web chat rooms are better accessed directly than through a cache. Your browser's proxy settings will probably allow you to specify a list of URLs or domains which it should accessly directly and not through the cache.

Setting up your browser to use the cache

NOTICE: If you are not dialed into or directly connected to the Datasync network, you will not be able to use this cache.

With modern browsers, you may either configure the proxy manually or use an automatic proxy configuration which is downloaded from the Datasync web server. The automatic configuration is easier whereas the manual configuration offers more flexibility. Specific instructions for popular browsers follow.
