How to call a RESTFul web service with a parameter that has a "dot" inside - web-services

Question

I developed a RESTFul service but I am having problems when I want to pass a parameter that has a dot in it. I tried encoding the URL, replacing the dot by %2E, but the end point is not found. When I remove the dot, the end point is found, so it is obvious that something is wrong with the dot.
for example, this request works:
http://localhost:9999/SvcLipigas.svc/AlmacenaPedido/229188562/16122016/2030/123456/CILINDRO%2015%20KGCODIGAS/2/14000/15/19122016/1514/19122016/1000
But this other one does not:
http://localhost:9999/SvcLipigas.svc/AlmacenaPedido/229188562/16122016/2030/123456/CILINDRO%2015%20KG%2ECODIGAS/2/14000/15/19122016/1514/19122016/1000
Notice the dot in the "CILINDRO%2015%20KG%2ECODIGAS" parameter.
Any help will be appreciated.
Currently, as a patch, I am sending the dot replaced by a pipe character, and in the service, I am replacing it back to the dot, but this is a very ugly solution.
EDIT:
[OperationContract]
[WebInvoke(Method = "GET",
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Wrapped,
UriTemplate = "AlmacenaPedido/{telefono}/{fechaPedido}/{horaPedido}/{codigoInterno}/{descripcionProducto}/{cantidadProducto}/{valorUnitario}/{kilosProducto}/{fechaEntrega}/{horaEntrega}/{fechaDespacho}/{horaDespacho}")]
int AlmacenaPedido(string telefono, string fechaPedido, string horaPedido, string codigoInterno, string descripcionProducto,
string cantidadProducto, string valorUnitario, string kilosProducto, string fechaEntrega, string horaEntrega,
string fechaDespacho, string horaDespacho);

Answer 1

This is a limitation of IIS.
It is treating the dot (encoded or not) as an extension.
Try adding
<httpRuntime relaxedUrlToFileSystemMapping="true" />
to the web.config
