Browser App Not sending HTTP request

We have developed a android browser application (javascript) which keeps (every 3Sec) on sending a http (GET) request to my REST server (hosted on TOMCAT).

Everything works fine till the time phone is in operation. But as soon as phone is lying idle, the browser application's javascript stops sending the HTTP requests.

The phone is connected with our test WIFI router, and in the phone setting we have kept WIFI connected even if phone goes in the idle state.

We are capturing HTTP packets with wireshark on the REST server machine. Till the time phone is in working state, we recieve HTTP request packet but as soon we leave the phone (and it goes to idle state) idle, HTTP packets stops appearing on the Wireshark (however some TCP packets are visible).

The same behavior is there on IPhone device as well, Is it the default behavior of SmartPhone browsers?

Please help if someone have faced this kind of situation or have similar experience.

PS. on android, the browser we are using is the default browser and android version is 4.0.3

Probably a precaution against sucking the device's battery and data plan empty. If this was a proper Android app you could convert this part into a Service to ensure it keeps executing.
