I have an Angular application. The frontend has a mechanism that periodically fetches some information like this:
````
ngOnInit(): void {
setInterval( () => {
this.http.get(... ).subscribe(
(data) => {
this.data: any = data;
}
}, 10000);
}
````
This gets handled in the backend by the service method
````
@GET
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Response getData(
...
````
I also have a function for refreshing the token declared like this:
````
@POST
@Path("/token")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response updateToken(String token) {
````
~~The problem is that I only want the token to be updated when the actual user is clicking around at the page. Not for this notifier.~~
I have come up with some possible strategies here.
1. Send some extra metadata in the url passed to this.http.get and somehow figure out how to extract that in updateToken
2. Adding a separate endpoint and somehow make this avoid triggering updateToken
3. Changing this.http.get to something completely different call
4. Making the server send updates periodically to valid tokens
But I have no idea how to start with any of these. Can you help?

How to prevent token from being refreshed

I have an Angular application. The frontend has a mechanism that periodically fetches some information like this:

````
ngOnInit(): void {
    setInterval( () => {
        this.http.get(...   ).subscribe(
            (data) => {
                 this.data: any = data;
            }
      }, 10000);
}
````

This gets handled in the backend by the service method

````
   @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Consumes(MediaType.APPLICATION_JSON)
    public Response getData(
        ...

````

I also have a function for refreshing the token declared like this:

````
    @POST
    @Path("/token")
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    public Response updateToken(String token) {
````

The problem is that I only want the token to be updated when the actual user is clicking around at the page. Not for this notifier.

I have come up with some possible strategies here.

1. Send some extra metadata in the url passed to this.http.get and somehow figure out how to extract that in updateToken

2. Adding a separate endpoint and somehow make this avoid triggering updateToken

3. Changing this.http.get to something completely different call

4. Making the server send updates periodically to valid tokens

But I have no idea how to start with any of these. Can you help?
