 What is a "cache?" How much RAM should I allocate to cache? |
| The cache is your browser's temporary storage system; it is designed to speed performance and reduce network traffic. When you request a page, your browser checks to see if it is already present in your cache. If not, the page is retrieved from the source and then stored in your cache. The next time you request that page, your browser retrieves it from your cache rather than fetching it again off the network. If the page has been updated in the interim, you will not receive the new page unless you click the reload button. When your cache is full, new documents requested will replace those documents that have least recently been used.
There are two types of caches: the disk cache and the memory cache. Both store information retrieved from the network--to your hard drive and RAM, respectively. When you shut down, your disk cache is preserved; your memory cache is not. Because documents are more quickly retrieved from your memory cache, you may be tempted to make it quite large. However, for performance reasons, the number of kilobytes allocated to your memory cache should not exceed 25 percent of your total RAM.

| Why aren't the images from Garage Cam updating? |
Your browser may be caching the images and not showing the latest available picture. To get the latest image, try right-clicking on the Garage Cam window and select reload or refresh while holding down the shift key. This should ensure you've got the most up-to-date image. Also, you can go to preferences/options and set your browser to check for newer versions of stored pages on every visit to the page.

| Why aren't all the images in my photo galleries showing up? |
The minute you click on a photo gallery, a process begins to preload all the images that you will see. If you click through the gallery before the photos have loaded, the process stops, and the photos appear to not have loaded. The amount of time depends greatly on your connection rate. If your photos do not appear, simply right click within the gallery and select reload. the process will restart and the photos will begin to load again.

| What browsers do you support? |
NASCAR.com uses many of the advanced features of HTML. Our video clips and daily audio feeds require the use of external applications to listen to the live audio and view videos. Therefore, to best experience NASCAR.com, you must use a browser that supports tables, forms, Java, and external viewers. We recommend that you download and use the most recent releases of Netscape Navigator or Microsoft Internet Explorer.

| What can I do to improve the speed with which I access NASCAR.com? |
| The following suggestions may help to enhance the performance of our service:
Check your modem to ensure it is at least 28.8bps, our minimum requirement. If you have a 56K modem, as do most of our users according to latest research, you often will actually connect at a speed less than that. 56K or better is highly recommended for any enjoyment of our video content at NASCAR.com, and there are increasingly affordable high-speed connections such as ISDN, DSL or digital cable available to your home.
Turn your graphics off--an option most browsers provide. This will significantly reduce the download time of graphics-rich pages by displaying only their text. Generally, you will find that we try to minimize the size of our graphics to reduce download time.
Clear your disk and memory caches. Also, check your memory cache setting to ensure it's no greater than 25 percent of your computer's total RAM.
Close any applications you are not using to increase the amount of RAM available to your browser.
Decrease your browser's verification frequency. If using Netscape, for example, set your cache preferences to verify one time per session, as opposed to every time you retrieve a page.
Note: Your Internet access provider may pass through many nodes before it is able to contact the servers. Unfortunately, as the number of nodes increases, your page retrieval rate will suffer incrementally.

| I am having trouble printing with Netscape/Internet Explorer, what can I do? |
| To a large degree your printing problems are not something that you can remedy through your browser. While printing problems could be caused by dozens of things, here are a few simple things you can try when troubleshooting. These tips are provided for Netscape and Internet Explorer users only.
The first thing you need to confirm is that you have your printer properly installed. If you can print from other applications then we will assume that your printer is properly installed.
The second thing that you need to to do is click on FILE|PAGE SETUP.
This will bring you to the browser printing options menu.
On the Netscape Navigator make sure that you have the "Black text" option SELECTED. Click OK. And resume efforts to print.
With the Internet Explorer confirm that you have the PORTRAIT option selected. Additionally, make sure that you have the proper PAPER SIZE selected. If you are unsure about paper size, select AUTO.
