Passing parameters via the url, or "query string" is incredibly insecure, because data can be edited in the address bar of the web browser, and unexpected results can occur.
But... here's how you do it.
Say your url is
And you need to pass two parameters, "month" and "day".
Use this url,
You separate the url and parameters with a question mark (?). Then you may have as many name/value pairs of parameters as you like, with the name on the left of the equal sign (=) and the value on the right.
Name/value pairs are separated by the ampersand sign (&).
If you're using ASP or CSP, you get at the values like this.
Declare a local variable, then assign the query string value to that local variable. Or, just reference the query string value directly.
DIM strMonth
strMonth = Request.QueryString("month"
DIM intDay
intDay = Request.QueryString("day"
Hope that helps!
