SUMMARY
This article provides a step-by-step overview of how you can set up a proxy server as a cache only server. You need to be running Windows NT 4.0, Service Pack 2 is optional, IIS 2.0 or 3.0, and Proxy Server 1.0 or 2.0. The Web proxy service must be running. Standard hardware required for Windows NT 4.0 and IIS 2.0 should be installed. Only one Netcard or adapter is sufficient because this computer will not be connected to the Internet.



MORE INFORMATION
To follow are the steps to configure the Web proxy service:


 * 1) Open the Internet Service Manager. Clicking the Start, select Programs, select Microsoft Proxy Server, and then select Internet Service Manager.
 * 2) Double-click or select the Web proxy service, click File, and then click Properties from the menu to bring up the properties dialog box. Click on the caching tab.
 * 3) Click to select the Enable Caching check box.
 * 4) Click to select the Enable Active Caching check box.
 * 5) Click the Change Cache Size tab under Cache size to change the cache size. For security purposes, set the cache on an NTFS partition.
 * 6) Click the Advanced tab. To limit the size of the cached objects, click the first check box and type in a number for the cache size. The "Return expired objects when site is unavailable" check box can be left checked or you can uncheck it.
 * 7) Click the Add tab under Cache filters.
 * 8) Enter an URL in one of the forms given. The filtering status can be left at the default.

This completes the setup on the server.

In your browser (IE 3.0 and above) click View, Options and Connection from the menu to Check the Connect through Proxy server check box and type in the name/address of the proxy server. Or you can right-click on the Internet Explorer (this will not work on Win 3.x and Windows NT 3.51 computers) and click Properties and follow the steps above.

By default, the cache cleanup interval and cleanup time are set to the following in the registry. If you want to make changes to these you have to edit these keys in the Registry.

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.   CleanupInterval DataType: REG_DWORD Range: 0-93a40(h) Default: 15180(h) Description: The interval size in seconds between each cache cleanup. The default setting is for every 86,400 seconds (24 hours).

CleanupTime DataType: REG_DWORD Range: 0-23 Default: 0 Description: Sets the hour of the day that cache cleanup is scheduled to  occur. The default is to set cleanup to occur at 12:00 A.M.
