How to extract variable + its value from URL

[Jozef Jarosciak]

I have url:
www.site.com/index?a=1&b=2
www.site.com/index?a=1

and I need a regex or some solution to extract 'a' variable and its
value.

Any ideas?

Quick and dirty:

\\\
Dim u As New Uri("http://www.site.com/index?a=bla&b=22312")
Dim w As New HttpRequest("", u.AbsoluteUri, Mid(u.Query, 2))
MsgBox(w.QueryString.Item("a"))
MsgBox(w.QueryString.Item("b"))
///

Thanks, but when I plug this to my code, line:

Dim w As New HttpRequest("", u.AbsoluteUri, Mid(u.Query, 2))

has a word HttpRequest underlined and saying:
"Type HttpRequest is not defined"

I made sure at the top it reads:
Imports System.Web

What is wrong?

Make sure your project contains a reference to "System.Web.dll".

Ah, of course :)
Thanks a lot. It works like a charm.
