facing a problem by sending data from one page to another page

I really thankful for your reply and i have some more clarification.

In this below setting path value is not a fixed one it is random you will get it from the sourcepage("Default.aspx")           (From the source page the will send some redirect page i need to set in the "Path")

                                                       path= "your page.aspx"
                                                       type = "youramesapace.myHandler"/>

how i can do it programmatically to set the path.

For Example:

My client will send some redirect page from sourcepage("Default.aspx") and I need to set that value into "Path" attribute of 

what are all the data i having in my source page  "Default.aspx" (ex: some textbox/dropdown values) that should be available in my redirect page also that we need to achieve thru "FORM POST" .

it is really urgent for me.

You can write a HTTP handler to leverage that

public class myHandler:IHttpHandler
{
     public void ProcessRequest(HttpContext context)
     {
         //TO DO leverage here you code
         //context.Request.....
           .......
         //context.Response....
     }
     public bool IsReusable
     {get{return true;}}
}

then in the config file

                                                       path= "your page.aspx"
                                                       type = "youramesapace.myHandler"/>

if you plan to deploy it then you have to register the given httphandler within the IIS meta data base
