12. Click URL in the Displayed Columns list and move it up so that it is third in the list. 13. Click OK. 14. On ISA1, open the Performance Console from the Administrative Tools folder. 15. Ensure that the Pages/Sec counter is selected and press DELETE. Press DELETE two more times, deleting all the performance counters. 16. Click Add (+) on the Performance Console toolbar. 17. In the Add Counters dialog box, in the Performance Object list, click ISA Server Cache. 18. Click All counters, and then click Add. 19. Click Close to close the Add Counters dialog box. 20. Press CTRL-R to switch the performance view to a report view. 21. On CLIENT1, open Internet Explorer and access http://www.microsoft.com. 22. Close Internet Explorer. 23. On ISA1, in ISA Server Management, click Stop Query. 24. Review information in the Cache Information and Destination IP columns. A cache information value of 800000 means that the content was retrieved from the Internet, but that the content is cacheable and that the response included the Last-Modified header. A destination Internet Protocol (IP) that is the actual IP address of the server on the Internet also indicates that the page was retrieved from the Internet. A value of 40840000 indicates that this content should not be cached because it contains the Cache-Control: No-Cache header or the Pragma: No-Cache header. A value of a00000 indicates that this content should be cached but it has a time limit defined. 25. Switch to the Performance Console. Notice that ISA Server has cached several URLs. 26. In ISA Server Management, click Start Query. 27. On CLIENT1, open Internet Explorer and access http://www.microsoft.com. 28. Close Internet Explorer. 29. On ISA1, click Stop Query. 30. Review information in the Cache Information and Destination IP columns for each of the Tailspin Toys URLs. A cache information value of 0 means that the content was retrieved from the ISA Server cache. A destination IP of 0.0.0.0 also indicates that the page was retrieved from the ISA Server cache.

Use the following questions to help determine whether you have learned enough to move on to the next lesson. If you have difficulty answering these questions, review the material in this lesson before beginning the next lesson. You can find answers to these questions in the Questions and Answers section at the end of this chapter. 1. You have deployed ISA Server 2004 and configured the server as a Web proxy server. All internal client computers are configured as Firewall clients. You enable caching on ISA Server, using the default caching configuration. After you enable caching, users report that they are getting more error messages when they try to access some Web sites. You investigate and determine that the error messages appear when a Web site is temporarily unavailable. Users continue to get the error messages for some time after the Web site is available. You need to ensure that the users can access the Web sites as soon as they are available on the Internet. How can you do this

2. You have deployed ISA Server and configured the server as a Web proxy server. After you enable caching, some users report that they get out-of-date information from a partner Web site. The Web site contains information that changes frequently, sometimes several times a day. The users say that the information from the Web site that they see is sometimes more than a day old. You must ensure that users always get the most recent information from the partner Web site, but you do not want to affect the caching configuration for other Web sites. What should you do a. Modify the cache settings so that data that has expired for more than 30 minutes will not be returned to the client. b. Create a cache rule for this Web site. Configure the cache rule to never cache content from the Web site. c. Create a cache rule for this Web site. Configure the cache rule to cache dynamic content. d. Create a cache rule that will apply to all Web sites except this Web site. Configure the cache rule to not cache dynamic content.
