For some reason it just started to happen randomly that any web application that sits behind our UTM and Web Application Firewall, we get random 400 Bad Requests. We have updated Apache on all the web front ends and still we are plagued with 400 bad requests. We have even gone as far as turning off the Firewall profiles that were enabled on the web application and still we keep getting random 400 bad requests. Any help with this issue would be great.
