RSP supports Java style comments within code sections. Specifically:
Example 3.2. RSP comments
<%
// A single line comment
boolean success = true; // A single line comment after a line
/*
A multiple line comment
%>You should not see this text in the output!<%
/* A nested comment */
/* This shouldn't be executed */
success = false;
// A single line comment inside the main comment - not special ignored
%>An unterminated HTML section, but inside the comment so it's ok
// The main comment termnates here --> */
%>
