New Post: Hide multiple params?

Hello,
I'm developing an UrlMaster provider for a custom Dnn module, and could get a first working version. My dll simpy tracks a specific parameter (an id, used to retrieve users profiles from the db) and uses it to build my friendly urls, e.g.:

/contacts/uid/12/Name-Surname.aspx

becomes

/contacts/Name-Surname

My problem is I need to map multiple parameters, that is my original url would be something like:

/contacts/uid/12/par2/somevalue/Name-Surname.aspx

Would it be possible to map this url to the same as above (/contacts/Name-Surname), but being able to retrieve all my vaiables (uid and par2) inside my provider?

I already set my FirndlyUrlInfo to keep a couple of values:

internal class FriendlyUrlInfo

{
    public int userid;
    public string displayname;
    public string param2;
}

and I fill them in in my SqlDataprovider, but then I miss what to do in my ChangeFriendlyUrl, where friendlyUrlPath only contains the former value (e.g. /uid/254).
Should I manually retrieve what I need inside this function?
