Fileupload blocked by ASM-policy

Hey there! I tried to set a wildcard parameter for this url to have the possibilty to use the "learn"-button. But the ASM won't recognise any parameter, cause there isn't one. It's the paylod itself that causes the problem. Remember, it's a put/post request and nothing i can handle through a get-parameter.

 

A big encrypted file is splitt into 1MB chunks and this chunks are transfered as the payload of this put-request.

 

I didn't expect, that it's so difficult to tell the ASM not using several Attack-Signatures on a payload for a specific url.
