Accessing Query string in postback event while using URL rewrite 2.0 in asp.net 4.0

Question

I am in a trouble working with URL Rewrite 2.0 (in IIS7) for Web form web-app. In application there are job postings whose URL was not earlier SEO friendly and not in readable form as

*"http:www.mySite.com/candidate/JobDetails.aspx?ref=h_hj&JobPostingID=10049"*

I wrote Inbound Rule for that page i.e. for JobDetails.aspx as

Pattern to match: ^candidate/JobDetails\.aspx$

Conditions : {QUERY_STRING} and pattern: ^ref=([^=&]+)&JobPostingID=([^=&]+)$

Action : type: Rewrite and Rewrite URL: {C:1}/{C:2}

And it gave me new url string as

http://www.mySite.com/h_hj/10049

Now the problems are

1) I am unable to get query string values from URL as it is giving me problem during post back event as "Input string was not in a correct format."

 if (!string.IsNullOrEmpty(Request.QueryString["JobPostingID"]))
            return Convert.ToUInt32(Request.QueryString["JobPostingID"]);

2) How to hide referral query string parameters only from URL as "ref" in my case.

you need to get those value with Route data

Access your RouteData variable using RouteDataand Also refer this link Asp.net Routing

int JobPostID= Convert.ToInt32(Page.RouteData.Values["JobPostingID"]);
// do Some fun with your JobPostID

Hey Thanx, but I am using url rewriting not routing, I used things you said and its giving error "Object reference not set to an instance of an object." as no value is assigning to it.
