    Hi Thiyagu , 
    you do not need to "else" statement , So try this : 

    when HTTP_REQUEST {
if { ( [string tolower [HTTP::uri]] contains "/..;/") } {
    HTTP::respond 200 content "not allowed..."
    drop
}
}

    And  output from my Lab : 

    > any request doesn’t contain "/..;/"  will Pass without issues. 
    so no need for "else" statement

    Regards
