Use httpPOST or httpGet in a Loop

[sniperwolfpk5]

Hi,
I want to use httpPost in Arduino loop. But it don't work. Can you tell or confirm whether it is working in loop?
If it is possible can you give me code how to do it. I need urgent help.

NOTE: httpPost is working only in Setup. But i want it to work in loop

What i want to do is to send ECG signals through httpPost and there a graph is generated from that ECG data.

Thx in advance.
