Dynamically generate ASPX page using C# and VB.Net in ASP.Net

hello there,

Consider the following situation:-

Suppose i have product lists where i have some products like

nike shoes black, denver deodrands, samsung on5

whenever i clicked on any product then weburl will look like

www.demo.com/nike-shoes-black.aspx

can any one tell me what is the concept or how to implement such kind of things where url dynamically changed as per I clicked on any on any product inspite of showing same page name.

please suggest me ..
