I am subscribing the&nbsp;F5-OWASP\_Managed then attach it to my AWS WAF. I am seeking a solution to block OWASP attack that happen on body. my question is: does the F5 managed rule group follows the AWS body size inspection limit (16 KB), or it has different limit? thank you

Hi&nbsp; @markovichi &nbsp;,  
The F5 managed rule group does not add or conttrol any size inspection limit. Such limits are attributes of AWS’s Web ACL. There are different limits enforced by AWS, but whchever you have shoudl remain the same when using F5 manged rule groups.

Thanks

Joel
