ASM Transparent mode blocking CORS requests
- Dec 16, 2018
Hi Hugo,
Thanks for the update. I agree, this is unacceptable. Never encountered something like this with ASM and I have dealt with CORS many times before. You can play with the CORS configuration through ASM or with an irule, I think that this is what I will do.
Stumbled upon very similar issue yesterday. When ASM is configured( simple profile ) even in transparent mode, users on mobile chrome receive CORS error on certain iframes. When ASM is disabled, everything works flawlessly. Need to verify if ASM is striping down the CORS headers...
I just had the same problem in my F5 BIG IP ASM 14.1.0.1. If I remove the WAF everything works flawless, I would expect at least the WAF in transparent mode to work but that isn't the case either...
