ASP QueryString Collection

Request.QueryString(variable)[(index)|.Count]

Example 1

To loop through all the n variable values in a Query String:

The following request is sent:

http://www.w3schools.com/test/names.asp?n=John&n=Susan

and names.asp contains the following script:

<%
for i=1 to Request.QueryString("n").Count 
  Response.Write(Request.QueryString("n")(i) & "<br />")
next
%>

The file names.asp would display the following:

John
Susan

Example 2

The following string might be sent:

http://www.w3schools.com/test/names.asp?name=John&age=30

this results in the following QUERY_STRING value:

name=John&age=30

Now we can use the information in a script: 

Hi, <%=Request.QueryString("name")%>. 
Your age is <%= Request.QueryString("age")%>.

Output:

Hi, John. Your age is 30.

If you do not specify any variable values to display, like this:

Query string is: <%=Request.QueryString%> 

the output would look like this:

Query string is: name=John&age=30
