unblock filetype for specific URL with matching expression

Break the monolithic if statement down into nested if statements, and add logging so you can see the results of each step

when ASM_REQUEST_DONE {
  if { ([HTTP::uri] starts_with "/abc/") } {
    log local0. "URI [HTTP::uri] starts with /abc/"
    if {([HTTP::path] matches_regex {*.[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]})} { 
	  log local0. "PATH [HTTP::path] matches the regex"
      if { ([ASM::violation count] >= 1) } {
	     log local0. "ASM violation count greater than 1 = [ASM::violation count]"
         if {[ASM::violation_data] contains "VIOLATION_OBJ_TYPE"} {
           log local0. "ASM violation data contains VIOLATION_OBJ_TYPE - unblocking"		 
           ASM::unblock 
		 }
	  }
	}
  }
