ASP.NET

Users will get to my site using a specific parameter, e.g. : http://www.mysite.com/whatever/?keepTrackOfThisValue=foo or http://www.mysite.com/who/cares/?keepTrackOfThisValue=bar

I would like to store the value of this peculiar parameter in Session everytime I found it in the QueryString. I'm currently using the Session_Start event in Global.asax in order to store this but I would like to override the value each time the parameter value change, which is not possible my way.

Where would you do this ?

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
