RE: Syntax and Performance

[horn_ken]

In terms of performance, little difference is caused by splitting
scriptlets (perhaps the extra print noted below.

However, this may be a typo on your part, but

  <%! String hostname;%>

declares an *instance* variable "hostname".
While this assignment:

  <%
    hostname    = request.getParameter("Host");
  %>

happens in the _jspService method. Essentially the hostname variable is not
thread safe. When accessing the hostname value, you will have a race
condition if the JSP does not implement SingleThreadModel.

I think it will generate a out.print("\n"); that is unecesary.
Why don't you look at the generated code?

   Is there any reason that I should not do this:

  <%! String hostname;%>
  <%
    hostname    = request.getParameter("Host");
  %>

  Does the compiler have to do any extra work? Should I combine them?
