Querystring

The querystrings are the parameters of a web-page. The querystring and the URL are separated by a question-mark (?). Querystring are often automatically made when one submits a form. You can also, however, create your own querystring in ASP or ASP.NET. You may see querystrings like

example.aspx?lang=en&size=10

The web-designer would most likely have made the lang querystring one that would have changed the language and the size querystring change the text size. You may have noticed that there is an ampersand (&) between the two querystring parameters. This separates the querystrings.
