    Hi MustphaBassim

    If "Detected Query String Length" is greater than "Expected Query String Length", the request is blocked.

    If the Detected Query String Length value is 48 and the "Expected Query String Length" value is 64, there must be no blocking for the request.

    You can review the article to change the "Query String Length" value.
