I'm getting a "Does not implement IController" error on images and robots.txt in MVC2
I'm getting a strange error on my webserver for seemingly every file but the .aspx files.
Here is an example. Just replace '/robots.txt' with any .jpg name or .gif or whatever and you'll get the idea:
The controller for path '/robots.txt' was not found or does not implement IController.
I'm sure it's something to do with how I've setup routing but I'm not sure what exactly I need to do about it.
Also, this is a mixed MVC and WebForms site, if that makes a difference.
You can ignore robots.txt and all the aspx pages in your routing.
routes.IgnoreRoute("{*allaspx}", new {allaspx=@".*\.aspx(/.*)?"});
routes.IgnoreRoute("{*robotstxt}", new {robotstxt=@"(.*/)?robots.txt(/.*)?"});
You might want to ignore the favicon too.
routes.IgnoreRoute("{*favicon}", new {favicon=@"(.*/)?favicon.ico(/.*)?"});
You can adjust the regular expression to exclude paths.
Haacked from the source.
The ignore route given above didn't work for me but I found a similar one that did:
routes.IgnoreRoute("{*staticfile}", new { staticfile = @".*\.(css|js|gif|jpg)(/.*)?" });
This error could also happen if inside a view in your area, you use the Html.Action helper. This helper will always use the area as a prepend, unless you specifically tell it not to. E.g.,
@Html.Action("Main", "Navigation", new { area = string.Empty })
I found another solution too... While I don't think I'll use it, it's worth showing here in the answers:
The following should (in theory) ignore looking for controllers for anything with a '.' in it.
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" }, // Parameter defaults
new { controller = @"[^\.]*" } // Parameter contraints.
);
