Description Michiel Overeem 2012-05-23 14:16:50 UTC
The behavior of the RouteCollection differs from Microsoft's implementation. Causing URL's to be catched by the wrong handler.

Problem 1. The RouteCollection.Ignore method.

Example code:

private static void RegisterRoutes(RouteCollection routes) 

  // other routes

On Microsoft .NET this rule causes url's like 
to be ignored. On mono however, these url's are not ignored.

Changing the Ignore rule to
  routes.Ignore("{*allcommand}", new { allcommand = @".*\.command(/.*)?" });
causes it to work correctly.

Problem 2. The catch all route.

Example code:

private static void RegisterRoutes(RouteCollection routes) 
  routes.Add(new Route("{*path}", new HttpHandlerRouteHandler<SomeType>());

  // other routes

On Microsoft .NET this route catches
http://somedomain.com/ and http://somedomain.com/Home

On Mono however, I need to add the following rule to catch the first url:
  routes.Add(new Route("", new HttpHandlerRouteHandler<SomeType>());

Are you still encountering this issue?
Comment 2 Michiel Overeem 2013-08-08 05:53:11 UTC
The differences between Mono and Microsofts implementation are still there.

But not all...

1) the route 
> routes.Ignore("{fileName}.command/{*pathInfo}");

now works the same on Mono and Microsoft

2) the route 
> routes.Add(new Route("{*path}", new HttpHandlerRouteHandler<SomeType>());

Still needs
> routes.Add(new Route("{}", new HttpHandlerRouteHandler<SomeType>());
on Mono

3) the route
>  routes.Ignore("Part/{*pathInfo}");
catches http://example.com/Part?arg=value with Microsofts implementation. On Mono however, those URL's are not catched.

This is all tested on Mono 3.2.1(MacOSX)
