To TopOpening the Administrative Interface for the Web Proxy Service

To open the administrative interface for the Web Proxy service

  1. From the server’s desktop, click Start, select Programs, and then select the Microsoft Proxy Server program group.

  2. Click Internet Service Manager.

    The Microsoft Internet Service Manager window is displayed.

  3. If necessary, connect to the server to be administered. From the Properties menu click Connect to Server and complete the dialog box that appears.

    This step is unnecessary if you are administering the local server.

  4. In the Microsoft Internet Service Manager window, click the server name next to the Web Proxy service.

    The Web Proxy Service Properties window appears. It contains tabs labeled Service, Permissions, Caching, Logging, and Filters.

The following table summarizes each Web Proxy service property sheet.

Property Description
Service Use the Web Proxy Service property sheet to display the product ID, to add a comment about the server or the Web Proxy service, to edit the Local Address Table (LAT), and to view information about current connections.
Permissions Use the Web Proxy Permissions property sheet to determine which users or groups of users are allowed to access the Internet through the Web Proxy service on a server. Permissions are granted separately for each supported protocol.
Caching Use the Web Proxy Caching property sheet to enable or disable caching of Internet objects, and to configure cache parameters.
Logging Use the Web Proxy Logging property sheet to set the logging options for the Web Proxy service. Microsoft Proxy Server can log information about all Internet requests made by clients. It can log to a text file or to a table in an ODBC-compliant database (such as Microsoft Access or Microsoft SQL Server).
Filters Use the Web Proxy Filters property sheet to allow or prevent client access to specific Internet sites. The filtering set here is common to both services. It applies to all users who access the Internet using the Web Proxy or WinSock Proxy services on the server.

To TopWeb Proxy Service Property Sheet

Use the Web Proxy Service property sheet to display the product ID, to add a comment about the server or the Web Proxy service, and to view information about current connections.

To open the Web Proxy

  1. In Internet Service Manager, open the Web Proxy service for the appropriate server, as described in Opening the Administrative Interface for the Web Proxy service.

    By default, the Service tab should be selected.

  2. If it is not already selected, click the Service tab.

The Web Proxy Service property sheet has the following elements:

To TopUser Sessions Dialog Box

Use the User Sessions dialog box to view the user name of all users who have recently sent Internet requests to the server, the time at which each connection was established, and the elapsed time since each connection was established.

To open the User Session dialog box

To TopLocal Address Table Configuration Dialog Box

Use the Local Address Table Configuration dialog box to create a list of the IP addresses that constitute your private network. The information you provide is used to create a table, called the Local Address Table (LAT), that defines your private network.

It is used to determine whether an IP address is on the private network, or is external. If the address is internal, the client connection is made directly. If the address is external, the connection is made remotely, through Microsoft Proxy Server.

To open the Local Address Table

The Local Address Table Configuration dialog box has the following elements:

To TopConstruct Local Address Table Dialog Box

Use the Construct Local Address Table dialog box to determine which IP addresses will be added to the Local Address Table (LAT).

To open the Construct Local Address Table Dialog Box

The Construct Local Address Table dialog box has the following elements:

To TopWeb Proxy Permissions Property Sheet

Use the Web Proxy Permissions property sheet to determine which users or groups of users are allowed to access the Internet through the Web Proxy service on a server. Permissions are granted separately for each protocol.

To open the Web Proxy Permissions property sheet

  1. In Internet Service Manager, open the Web Proxy service for the appropriate server, as described in Opening the Administrative Interface for the Web Proxy service, earlier in this appendix.
  2. Click the Permissions tab.

The Permissions property sheet has the following elements:

The available protocols are:

To TopWeb Proxy Add Users and Groups Dialog Box

Use the Add Users and Groups dialog box to grant access to the selected protocol to a user or to a group. You can grant access to users and groups from this server, from the local domain, and from trusted domains.

Tip   It is a good idea to use User Manager for Domains to create a user group containing the user accounts of all users who need access to WWW, FTP, or Gopher. Then, for each protocol, you only have to apply permissions once for the entire group, rather than for each individual member. For more information about user groups and about User Manager for Domains, see your documentation for Windows NT.

To open the Add Users and Groups dialog box

  1. In the Web Proxy Permissions property sheet, select a protocol from the Protocol box.
  2. Click Add.

The Add Users and Groups dialog box has the following elements:

To TopWeb Proxy Caching Property Sheet

Use the Web Proxy Caching property sheet to enable or disable caching of Internet objects, and to configure cache parameters.

In this property sheet you can set the location and size of the disk cache. The disk cache stores a copy of each object that a client requests from the Internet in an area of the hard disk called the cache. When a second request is made for the same object, Microsoft Proxy Server fulfills the request with the copy of the object in the cache.

The cache can operate in either a passive or an active mode. In the passive mode, it copies each object requested from the Internet to the hard disk of the computer running Microsoft Proxy Server. In the active mode, it updates objects in the cache periodically. You can specify how often to update the cache.

Using an object from the cache:

To open the Caching property sheet

  1. In Internet Service Manager, open the Web Proxy service for the appropriate server, as described in Opening the Administrative Interface for the Web Proxy service.
  2. Click the Caching tab.

The Web Proxy Caching property sheet has the following elements:

To TopMicrosoft Proxy Server Cache Drives Dialog Box

Use the Microsoft Proxy Server Cache Drives dialog box to specify the disk drives that will be used for caching, and the amount of space on each drive that will be allocated to caching.

The disk cache should always be located on one or more hard drives installed on the computer running Microsoft Proxy Server. (You cannot use network drives to store cached data.) You should choose hard disks of sufficient size, and make the cache as large as possible. Using multiple drives is a good idea, because breaking a very large cache into several smaller caches can sometimes speed access to objects. To help prevent a from disk filling up, it is a good idea to store the logs and the cache on different volumes.

When configuring the cache drives you must, at a minimum, allocate at least one drive and 5 MB for caching. However, the recommended minimum allocation is higher. It is suggested you allocate at least 100 MB plus 0.5 MB for each Web Proxy service client (and round up to the nearest full megabyte). For example, if a server will be servicing 79 Web Proxy service clients, it is recommended you allocate 140 MB or more to the cache. For each server the optimal cache allocation will vary depending on load and configuration, but in general, increasing the disk space allocation benefits the cache.

Allocate space from a drive to the cache in increments of 5 MB. If you assign a number to the cache that cannot be evenly divided by 5, the allocation is rounded down to the next lowest 5-MB increment. For example, if you assign 194 MB to the drive C:, 190 MB is actually allocated from that drive to the cache.

To open the Microsoft Proxy Server Cache Drives dialog box

The Microsoft Proxy Server Cache Drives dialog box has the following elements:

To TopAdvanced Cache Policy Dialog Box

Use the Advanced Cache Policy dialog box to:

To open the Advanced Cache Policy dialog box

The Advanced Cache Policy dialog box has the following elements:

To TopCache Filter Properties Dialog Box

Use the Cache Filter Properties dialog box to specify a URL whose objects will not be cached. Or, use this dialog to specify a URL whose objects will be cached regardless of other filters. (You will usually do this when you have already specified a wildcard filter to deny caching of all Internet objects from a site, and want to re-enable caching of objects from a particular sub-tree of the site.)

To open the Cache Filter Properties dialog box

The Cache Filter Properties dialog box has the following elements:


To TopWeb Proxy Logging Properties

Use the Web Proxy Logging property sheet to set the logging options for the Web Proxy service. Microsoft Proxy Server can log information about all Internet requests made by clients. It can log to a text file or to a table in an ODBC-compliant database (such as Microsoft Access or Microsoft SQL Server).
