WCF WebGet UriTemplate for any file path

Question

I've implemented a self-hosted local web server using WCF as per this article: Developing Web 2.0 User Interface for Self Hosted WCF Services using HTML5, CSS3 and JQuery

In real world applications, I've found that I needed to make the following modifications in order to handle deeper pathing to sub-folders. This works for my current needs because I simply created enough UriTemplates to get 6 folders deep. However, I suspect there must be a more elegant way to handle this that will allow any number of sub-folders to be served.

I tried to figure something out with wildcards (e.g. /{*path}/{resource}.{extension}) but it seems wildcards are only permitted in the last segment of the path.

Any help would be appreciated,

Ken

Why not just use something like this...

[OperationContract]
[WebGet(UriTemplate = "{*pathname}")]
public Stream Links(string pathname)
{
    string path = Path.GetDirectoryName(pathname);
    string resource = Path.GetFileNameWithoutExtension(pathname);
    string extension = Path.GetExtension(pathname).TrimStart('.');
    return Links(path, resource, extension);
}

I use [WebGet(UriTemplate = "{*pathname}")] test myself.

And the url='http://localhost:50923/OMSService.svc/Links?seller=s001&service=s2&timstamp=324&user=uo&pass=009',

and then why the pathname='Links'.It means that the pathname is the called method name ,

is not the long string 'seller=s001&service=s2&timstamp=324&user=uo&pass=009'!

Thanks in advance !
