I'm trying to setup a simple random image script to allow other websites to
display random banner ads located on my server.
The other website would call the perl script in an <img> tag, like so:
<img src="http://www.my_site.com/cgi-bin/random_banner.cgi"; width="468"
height="60">
I've tried several perl scripts that basically work, but the problem is
always the same with all of them: the browser always caches
'random_banner.cgi' causing the same banner to be displayed on every
subsequent page. The only way to see a different banner is to hit
Reload/Refresh.
Is there a script out there that avoids the cache problem in displaying
random banners via an <img> tag?
Thanks!
Use a "Cache-control" header that specifies "no-cache" and use an
Expires header that uses a date in the past.
