c# - Dynamic Routing in asp.net webforms -

can add dynamically routes global.asax file

suppose if have multiple routes same page example

• http://website.com/about
• http://website.com/en/about
• http://website.com/en/about-us

while actual url page http://website.com/en/about-us.

my question is: there way can dynamically define these routes in global.asax file in such way reads url entered users http://website.com/about , compares database table , redirects correct page http://website.com/en/about-us?

taking consideration following table structure:

id  url_name    url                                 actual_url                              page_handler 1   home        http://website.com/                 http://website.com/                     default.aspx 2      http://website.com/about            http://website.com/en/about-us          about.aspx 3      http://website.com/about-us         http://website.com/en/about-us          about.aspx 4      http://website.com/en/about         http://website.com/en/about-us          about.aspx 5   contact     http://website.com/contact          http://website.com/en/contact-us        contact.aspx 6   contact     http://website.com/en/contact       http://website.com/en/contact-us        contact.aspx 

right have configure each route manually in global.asax:

        if(httpcontext.current.request.url.tostring().tolower().equals("http://website.com/about")         {             httpcontext.current.response.status = "301 moved permanently";             httpcontext.current.response.redirect("http://website.com/en/about-us");         }           if(httpcontext.current.request.url.tostring().tolower().equals("http://website.com/en/about")         {             httpcontext.current.response.status = "301 moved permanently";             httpcontext.current.response.redirect("http://website.com/en/about-us");         } 

a pointer example or solution highly appreciated.

i find routes in global.asax great static resources if want nice, sexy extensionless urls seo.

for dynamic pages/urls though, tend have catch route handles request if doesn't match static routes.

eg

    // ignore     routes.add(new system.web.routing.route("{resource}.axd/{*pathinfo}", new system.web.routing.stoproutinghandler()));      // sexy static routes     routes.mappageroute("some-page", "some-sexy-url", "~/some/rubbish/path/page.aspx", true);      // catch route     routes.mappageroute(        "all pages",        "{*requestedpage}",        "~/assemblerpage.aspx",        true,        new system.web.routing.routevaluedictionary { { "requestedpage", "home" } }     ); 

so, when request comes in checks each static route in turn , executes specified page. if no match found, drops through catch , assemblerpage.aspx handles request. assemblerpage analyse requested url , redirect, rewrite path or stick controls on page render - basically, can whatever want do.

in case, i'd have assemblerpage check db , compare requested url urls in table. redirect or rewrite path.
