Figure 6-3. SSI inserted banner ad eliminates JavaScript includes

Chapter 6 - Web Page Optimization

For advertising, you can eliminate the extra HTTP requests required by the preceding methods by using a server-side include-based ad delivery system such as 24/7 Real Media’s Open AdStream (http://www.247realmedia.com). Here is some sample code from Internet.com that can be added to a web page to include a banner ad:

<!--#include virtual="/banners/adstream_sx.ads/_PAGE_@750x100-1"-->

This technique uses server-side includes (SSIs) to include the banner ad directly into the page, saving an HTTP request. The inserted code looks like this:

<div id="topvisibility"><table ALIGN="CENTER">
<tr>
<td align="center">
<A HREF="http://itmanagement.earthweb.com/RealMedia/ads/click_lx.cgi/intm/it/www.
datamation.com/datbus/article/3739896i/1286136569/468x60-1/OasDefault/SSO_BluRay_
GEMS_1d/bluray2_750x100.jpg/34376565343564363437666663326530" target="_top"><IMG

34376565343564363437666663326530?_RM_EMPTY_" Width="1" Height="1" Border="0"></td>
</tr>
</table>
</div>

The resultant ad displays as shown in Figure 6-3, saving an HTTP request.
