How to share same address for multiple endpoints

I have created REST service with WCF and i have different contracts(Contract1, Contract2, etc..). This is configuration in web.config

<endpoint address="users" binding="webHttpBinding" behaviorConfiguration="web" contract="FilmInfoApi.Service.IUserService"/>
    <endpoint address="actors" binding="webHttpBinding" behaviorConfiguration="web" contract="FilmInfoApi.Service.IActorService"/>
    <endpoint address="films" binding="webHttpBinding" behaviorConfiguration="web" contract="FilmInfoApi.Service.IFilmService"/>

It's the example of contract.

[OperationContract]
    [WebGet(UriTemplate = "?offset={offset}&count={count}", ResponseFormat = WebMessageFormat.Json)]
    Films GetFilms(string offset, string count);

So my question is how i can use same address for all endpoints (localhost/rest). Because i need contract UriTemplate more flexible, for example if i need return list of films by category (uri example: localhost/rest/category/2). But with this uri and current configuration (address property in web.config) I must put this method into Category contract. But in mine opinion this methid must be in Films contract. So does it has solution or it's normal?

If you want to expose multiple contracts with a single endpoint, then you have to have one of the contracts inherit from the other one. Then have your endpoint expose the derived contract. Like the following:

[ServiceContract]
IFilmService : IActorService

Then have one endpoint:

<endpoint address="rest" binding="webHttpBinding" behaviorConfiguration="web" contract="FilmInfoApi.Service.IFilmService"/>
