URL rewrite urlrewrite

Why URL rewriting?

1, in favor of SEO, with parameters of the URL lower weight;
2, the address looks more formal, the promotion UID

Pseudo-static: Looks like a normal page, not a dynamically generated page.
Principle: Read Request.url The requested URL (view-3.aspx) in Global.asax Application_BeginRequest
Then rewrite it with HttpContext.Current.RewritePath (Rewriteurl) (that is, by another page to process the request) (view.aspx?tid=3 format)

You can also use Microsoft's Urlrewrite, as long as you modify the configuration file can be URL rewrite

Case: URL rewrite, rewriting view-3.aspx and the like to view.aspx?id=3

1.view.aspx.cs design, Lbmsg is a server-side lab control

stringid = request["ID"]; if(id! =NULL)          {              intval =Convert.ToInt32 (ID); Switch(val) { Case 1: Lbmsg. Text="First place! It's you! ";  Break;  Case 2: Lbmsg. Text="the second is the best! ";  Break;  Case 3: Lbmsg. Text="Although you are the third, I believe you can succeed! ";  Break; default: Lbmsg. Text="The Revolution is not yet successful! Comrades still need to work hard! ";  Break; }          }

2.global.asax Design

protected voidApplication_BeginRequest (Objectsender, EventArgs e) {Regex reg=NewRegex (@". +view-(\d+). aspx");//defines a regular expression that () can be used to group       varMatch = Reg. Match (HttpContext.Current.Request.Url.AbsolutePath);//URL path matching the current user input       if(Match. Success)//determine if the match is successful        {          stringid = match. groups[1]. Value;//get the first set of valuesHttpContext.Current.RewritePath ("view.aspx?id="+ ID);//redirect pages, transfer requests        }    }

3. When the user input view-3.aspx, automatically when the view.aspx?id=3 processing
