Way to increase the HTTP unparsable request length in ASM policy

Hi, in our ASM policy we are getting the HTTP Protocol Compliance failed > unparsable request length violation. In the event logs it states that the URL length has exceeded the maximum limit of 2048. Is there a way to increase this limit in the ASM instead of accepting(disabling) this violation?

  • are you sure it is unparsable request length violation? because that seems a combination of Unparsable request content and request length.
  • Yes, it is the unparsable request content violation only. (attached)

  • Hi!

     

    You can modify in this menu: Security ›› Options : Application Security : Advanced Configuration : System Variables : ecard_max_http_req_uri_len

     

    And you must restart ASM service: tmsh restart sys service asm

     

    Regards
