Perform Http get method in Angular with no retries and wait until server sends the response?

Question

I have the following in my controller, in a Spring-Boot application:

@RequestMapping(method=RequestMethod.GET,value=\"/info\")
public DataModel getinfodata()         


        

Answer 1

Eventually, I figured out why it is happening The dev-server makes use http-proxy-middleware package More Here and the proxy options provided in this package is from underlying http-proxy library http-proxy options. one among them is

proxyTimeout:

timeout (in millis) when the proxy receives no response

The default value is ~120 seconds(based on my observations) if the server fails to respond within the stipulated time(120s) a new request is made to the server. overriding the default timeout with "timeout":30000 in proxy config file resolved the issue.

{
  "/info": {
     "target":  {
       "host": "localhost",
       "protocol": "http:",
       "port": 8080
     },
     "secure": false,
     "changeOrigin": true,
     "logLevel": "debug",
     "timeout":30000
  
  }
}
