Hi Moondaddy,

>From your description, one of your ASP.NET web page will checking a certain
querystring parameter in the requested url and do some session operations
depending on the parameter value. And currently you want to remove the
certain parameter from the request url if it exist in the first request, so
that the following postback request won't do the duplicated operations on
the session ,yes?

As far as I know, the QueryString collection of the Request object are not
modifiable by user, and I think you can consider the following means:
1.Still let the querystring param remain in the url and use the
Page.IsPostBack property to check whether its the first time loaded or post
back request so as to determine whether to do the session modification or
not.

2. User Server.Transfer or response.Redirect to reload the current page
with the non-querystring url. But this will reduce the performance.

Please have a consider on the above things. If you have any other different
ideas, please also feel free to post here. Thanks.
