Default URL Routing

I've successfully created a routing class which re-routes urls when someone types in: http://myurl/myfolder/{someletter}. This allows people to get some data from a database which starts with {someletter}, e.g. "a".

The folder called "myfolder" above contains a file in it's root called "default.aspx", e.g. http://myurl/myfolder/default.aspx which is just a signpost page and contains alphabet links to direct people to the url above. This all works fine.

However, I encounter a problem when I add another entry to the routing table which adds an extra level, e.g:

http://myurl/myfolder/{someletter}/{somearticle} (So people can get a specifIc article under that letter).

For some reason whenever i browse to http://myurl/myfolder/ it tries to route to: http://myurl/myfolder/{someletter}/{somearticle} for some bizarre reason? Does anybody know why this is?

I've stepped over the code in my class which handles the RequestContext and implements IRouteHandler and I can see it trying to route when I just browse to "myfolder".

Here's my code:

privatevoid RegisterRoutes(RouteCollection Routes)

System.Web.Routing.Route r1 = new System.Web.Routing.Route("myfolder/{someletter}", new UrlRouting.MySimpleRouteHandler());
System.Web.Routing.Route r2 = new System.Web.Routing.Route("myfolder/{someletter}/{somearticle}", new UrlRouting.MySimpleRouteHandler());



protectedvoid Application_Start(object sender, EventArgs e)

I cannot work out why this is occurring. Any help would be much appreciated....

After doing some additional reseearch, I've noticed if I add a folder reference betwen {someletter} and {somearticle}, the routing works fine, e.g.

System.Web.Routing.Route r2 = new System.Web.Routing.Route("myfolder/{someletter}/anotherfolder/{somearticle}", new UrlRouting.MySimpleRouteHandler());

Is it the case that you can't route to same folder with multiple {parameters}? Hope somebody can help me with clearing this up.

There is a global variable in PHP that holds the current domain name.


Here's an example using strpos that prints a different h1 tag depending on which domain is typed in the browser.

if( strpos( $_SERVER[ 'HTTP_HOST' ], "xxxx.com" ) !== false )
echo "<h1>xxxx.com</h1>";
elseif( strpos( $_SERVER[ 'HTTP_HOST' ], "yyyy.com" ) !== false )
echo "<h1>yyyy.com</h1>";

You could also embed this in a function to make the code cleaner.

function fromDomain( $domain ) {
if( strpos( $_SERVER[ 'HTTP_HOST' ], $domain ) !== false )
return true;
return false;

if( fromDomain( "xxxx.com" ) )

Hope this helps.
