Considering Comments in ASP.Net webpage.

“Even small thing make a big difference”, to prove this, commenting content in ASP.Net webpage page can be done using two methods.
1)<!—Normal HTML comment --><br /> 2)<%-- ASP.NET Comment --%>

Important and considerable difference between these two comments were, with HTML comments, content commented get rendered when web page requested and result in increasing download size. So its good to use ASP.NET comments.
