ASM: Block AJAX call in Transparent and Block mode, no logs exist

Hello.

I am facing difficultly implementing application security policy on a particular website.

The application is making a AJAX call to get some data. Sometimes it works, sometimes it hangs when the ASM is either in transparent or blocking mode. Disabling the ASM policy completely results in the AJAX call never hanging.

I know, I didn't believe it at first. However, we went through three rounds of blocking --> try the AJAX call, transparent --> try the ajax call, no blocking --> try the ajax call and the behavior was completely repeatale.

There are no logs of the apparent blocking behavior in the application security policy learning logs, the event logs, or the logs under the Logs -> security tab. I am on a 11.2 release version.

Any ideas?
