    Hello, I'm sorry, but your question is about where you could set the maximum size of a POST? Respectfully.

    In what context?

     

    You can set 'POST Data Length' in context of allowed file types under:

     

    Security ›› Application Security : File Types : Allowed File Types ›› Add Allowed File Type...

     

    If the filetype in a Request does not match any type in "Allowed File Types" list then ASM uses Zero as the default size..
