Unparsable request content - which security tradeoff ?

Hi Aurel and santoshmashetti  , 

The best security tradeoff is to define this URI(s) in ASM Microservices and disable HTTP compliance check under this URI only. 

Look at here for more details :

https://techdocs.f5.com/en-us/bigip-14-1-0/big-ip-asm-implementations-14-1-0/working-with-bigip-security-policy-microservices.html

doing this narrow the attack service for your device and provide an optimal tradeoff for your policy. 
But make sure this length is valid in the violation is a false positive.

Thanks
