Question

I don’t know how to put the title but i will try to explain it the requirement here.

Normally user entered an URL in address bar in browser, for example http://www.example.com, then click a link and redirect to another page http://www.example.com/test.aspx. Alternatively, user also can just enter/type http://www.example.com/test.aspx from address bar if they know the full path.

So, i required to write a code where user can type an URL in address bar, for example http://www.example.com/test.aspx?usr=”www.test.com”. (note: with addition usr=”www.test.com”)

The “usr=”www.test.com” after http://www.example.com/test.aspx? contain a value that stored in database.
So, when the user type http://www.example.com/test.aspx?usr=”www.test.com” it will search the database for matching http://www.test.com and do some process if found.

How can i achieve this.

You have to use Request.QueryString to get value any param passed to the page.
The result, stored in a page variable, can be used to retrieve the needed data.

string usr = Request.QueryString["usr"];
