This issue occurs with flash ads containing hard-coded links.
The problem with IE 6 (have not tested in 7) is that once the total characters in all the links exceeds a certain limit (I think it is 2048), the ad will not appear. Works fine in safari and firefox.
OpenAds tacks on about 140 characters per hard-coded link on our set up (all based on the URL of the server, etc)
To determine if we are going to exceed the limit, we take the number of links in the ad, multiply by 140 and add the length of all the URLs.
And we thought we'd never use algebra.
IE is obviously the limiter here, but changing the JS code that gets delivered to the browser could extend the usability. In the end, IE will still bite us in the butt.
Or we can give the advertiser some choices:
- fewer links in the ad
- fewer links tracked (only track some of them)
- convince everyone that IE 6 is a POS browser (IE 7 has not been tested against this problem) and switch to firefox
