We have a page that is a search engine friendly page if you link there from our site.  When you do, a cookie is written to remember you last visit.

The problem is that if you land on this page with out clicking on of our links first, the search engine friendly url is not reproduced.  How may I rewrite the URL on the fly to model the search engine friendly url we need?

Is this possible?  The page class has an Init and Prerender stage, but not BeginRequest where I understand the UrlRewriter to work.  I do not have to use the rewriter, per se, I just need to change the response url on the fly the the page is initialized or pre-rendered.

Thank you,

I recently implemented the poker league name (as per Ifinity's Friendly URL blog) in my poker league software and faced this issue. It needs to do a 301 redirect for all old links. Here is the code I use to handle it.

So

http://www.pokerdiy.com/Leagues/PokerLeague/tabid/514/LID/241/Default.aspx becomes http://www.pokerdiy.com/poker-league/lid/241/Rods-Sydney-Poker-League.aspx but if you request that first URL it needs to punt it on to the new URL.

        public void CheckFriendlyURLandDoRedirect(int itemID, string itemName)
        {
            //check the URL to make sure it is in the FriendlyURL format
            HttpContext context = HttpContext.Current;
            string originalUrl = context.Items["UrlRewrite:OriginalUrl"].ToString().ToLower();

            if (!originalUrl.ToLower().EndsWith(Utilities.formatTitle(itemName).ToLower()))
            {
                string rewrittenUrl = String.Empty;
                rewrittenUrl = GetLeagueDetailURL(pmb.TabId, itemID, itemName);
             }

                //only put out the reason if the debug header is passed in
                bool stDebug = Convert.ToBoolean(context.Request.Headers["_stdebug"]);
                if (stDebug)
                {
                    context.Response.AppendHeader("STX-Redirect-Reason", "Smart-Thinker League Redirect");
                }
                context.Response.Status = "301 Moved Permanently";
                context.Response.AddHeader("Location", rewrittenUrl);
            }
        }
