| [ Total number of ads: 9 | Chosen ad: 3 | Ads File | Choosing engine] |
This example of an ad rotation engine is implemented completely through HTML and ESI.
It consists of two files: "ads.html" contains a list of ads and links, "choose_ad.html"
contains the logic for choosing a random advertisement. Because logic is implemented on the edge,
all of the pages are cacheable. Click Reload to see a different ad.
