ASM JSON/XML payload detection & Automatically detect advanced protocols

Yes. You must use a Content Profile and assign it to a URL (or the URL wildcard). ASM attempts to classify the POST payload type automatically. Classification is based on the Content-Type header, and can be one of the following payload types:  

    •   text/xml
    •   application/xml
    •   text/x-json
    •   application/json

    In v13.1, ASM will classify these profiles automatically, and you will see a learning suggestion to add the profile based on what ASM sees in the payload. In the GUI, check the Properties of the URL, then click the Header-Based Content Profiles tab at the bottom of the section.
