Current behavior

I understand that is highly recommended to not use this tool when looking for support, but after spending hours of search and attempts to solve this issue, I don’t have any other option but ask the community here. In angular 2 beta.9-12 there was a way to use a regular expression to determine if some component should be used:

{   regex: '[a-z]+.[0-9]+',
    serializer: (params) => `{params.a}.params.b}`,
    component: MyComponent }  

This option is not available anymore (“@angular/router”: “3.1.0”), so I’m struggling to redirect some urls do the right component. For instance, I can’t distinguish between the two routes:

{ path: ‘:categoryUrl/:productUrl’ } -> goes do product.component { path: ‘:categoryUrl/:page’ } -> goes to category.component

Expected behavior

Router should provide a way to let us specify regular expressions to define if some route should be activated or not.

What is the motivation / use case for changing the behavior?

Keep organization of urls, specially keep existing SEO ranking.

Please tell us about your environment:

• Node (for AoT issues): node --version =

Is there any place that I can see how to use this new matcher? I read the part in API reference and the link for UrlMatcher seems broken.

Any chance to add gist by @matanshukry to the official documentation? As far as I can see a link to documentation for urlmatcher on the official documentation for router is still broken: broken url.
