Irule for disabling CORS functionality.

you should remove this text from your irule:

1. class allowed_origins {
2. ".example.com"
3. ".example2.com"
4. ".goodpartner.com"
5. }

^-this was an example of a datagroup called "allowed_origins" which you should create (easiest way is to do it via the F5 GUI):

Local Traffic -> iRules->DataGroups and instead of ".example.com" you should put your domain (mind the first dot which is needed in this case)
