I am with the following problem, I make an ajax call to my service and it returns me a paged list everything ok.. And I have a button where I download to excel, only because it is a very heavy table and I have no way to page this in excel I end up having the error of time out in the return of my call ajax.

I have heard of a stop you make the call and while the service is processed I have another service asking if it is finished and when it is finished returns to the customer, but n have idea of the name of this call or if there is any better way to accomplish this..

Can someone please help me ?

  • You’re talking about Partial-Content?

  • Why don’t you simply serve the excel file without ajax?

  • @Renan then I have to make the call ajax pq my UI does not process anything she asks everything for my service so I need the ajax to make the right call?

  • @Gabrielrodrigues if you are able to use ajax, you are able to redirect to the file URL, which is much simpler. Then the browser downloads the file quietly.

There are several ways to implement such a mechanism, called asynchronous process, where the processing of a heavy task takes place in parallel with the original request. A standard flow could be described as follows:

  • The task T1 is requested by the client C1.
  • The server initializes a thread in background where the task starts running. It assigns an ID to this process - for example, ID1.
  • The server returns the process ID to the client, allowing it to continue to be used by the user.
  • From time to time the client asks, for the server, what is the execution status of the task ID1; return can be, for example, 'cancelled', 'running' or 'finished'.
  • If finished, the server can return the content generated by the processing in background.
