ASP.net - Query-String Caching (VaryByParam)

Question

In what situations should we use Query-Strings (VaryByParam) to achieve caching in ASP.NET?

Can someone give an example of a real situation in the case of a web application?

Answer 1

Products.aspx?productID=12345

Obviously, you do not want the Product.aspx output cache to have data for the first product requested.

More details

Products.aspx?productID=12345, , 12345 . Products.aspx?productID=54321, , products.aspx , 12345. . VaryByParam .
