ASP.Net MVC: "Random" URLs getting generated by URL.Action
- by Daniel Magliola
I have 2 very similar routes, just because i'm trying to generate two different URLs for the same resource (same Controller/Action), and both are very similar.
These are the routes definitions:
routes.MapRoute("Post2.Mp3", "sites/{siteSlug}/post/{brand}/aconstant-{slug}.mp3", new { controller = "Posts", action = "Mp3" }, new { siteSlug = @"[A-Za-z0-9-_]+", slug = @"[^(aconstant\-)][A-Za-z0-9-_]+", brand = @"[A-Za-z0-9-_]+" });
routes.MapRoute("Post.Mp3", "sites/{siteSlug}/post/{slug}.mp3", new { controller = "Posts", action = "Mp3" }, new { siteSlug = @"[A-Za-z0-9-_]+", slug = @"[A-Za-z0-9-_]+" });
"brand" is going to be my site name, which is the same as "aconstant" in those routes.
Now, if I try this:
Url.Action("ShowMp3", "Posts", new { siteSlug = post.Site.Slug, slug = post.Slug, origin = "origfeedwithaudio", brand = "aconstant" })
sometimes I get the URL I expect:
/sites/site-Name/post/aconstant/aconstant-post-Name.mp3
but sometimes, I get this:
/sites/site-Name/post/post-Name.mp3?brand=aconstant
By sometimes, I mean that different sets of "slugs" give me one or the other.
I haven't seen the same set of slugs give me different URLs.
I haven't found any reasonable rule for when i'm getting one or the other, it seems random.
What is going on here?
How can I be getting different URLs based on esentially the same arguments?
Thanks!
Daniel
