    Hello,

    The rule mentioned is related to cross-site scripting. Unlike traditional, full blown WAF security solutions, the content and detailed descriptions of F5 rules cannot be viewed.

    If the rule was blocking legitimate traffic, you can disable it.

    I hope this helps

    Thanks

    Joel
