My system has some addresses that are called from other websites (not mine) and these websites, in this case, have a lot of subdomains.
Is it possible to purge without passing the origin? Because I don’t know all the subdomains these sites are going to call from. Resulting in x.site.com having the last version and y.site.com having an outdated one.
If it’s not possible, I saw that the enterprise plan has the purge from tag options, how many tags can I have? Because I would need one for each of those sites and would it work?
ps: I don’t think the prefix option would help, I would need a suffix one
In your case, I would expect you to set a tag to the value of the URL, and then purge that tag.
There is an easier option though. Are you setting appropriate CORS headers, or just setting Access-Control-Allow-Origin: *? If you are just setting *, then I would use a Transform Rule to remove the Origin request header from the requests. This would essentially collapse all the requests for the same asset into one cached object, which would purge using the normal single file purge.
