We have application (OHDSI Atlas- http) deployed on Azure Cloud (ISAS). We have set up of WAF in prevention mode. The application is working since last 8 months. Suddenly since last 2 weeks we are getting 403 for PUT and POST requests. Mostly looks like SQL injection rules and some Protocol related.
We had also raised request with MS support, and we had disabled some of the rules. It was working properly, but again started getting different rule hits.
Note- Recently, When we had added one more application to same application gateway with https. Is this can affect the other application?
