browser - Does Akamai resubmit on timeout -

we have application behind akamai meaning traffic goes first akamai, our web server, our app server. there few urls lengthy updates in our app , can take on 4 minutes depending on user submits (yes know horrible legacy code - did not write have deal it). url uses post request rather if matters. noticed if url takes more 2 minutes see url gets called on our app server every 2 minutes though browser has 1 request in network tab (same thing happens in both ie11 , chrome 45 dont think browser issue). lets url takes 6 minutes see 3 calls in our access logs.

we contacted akamai support , deny causing issue. provided logs shows 3 calls being sent server ours (each 1 2 minutes apart). need prove in fact akamai causing issue (because tech support not believe 1+1=2 unless prove them).

i've tried debug fiddler (an http packet sniffer). see 1 request coming browser see keep alive call every 1 minute in fiddler. assume not mean browser resubmitting request , http standard keep socketed connection alive.

ive searched akamai documentation , ive searched google cant find referring issue. have 2 questions really:

1). there way browser somehow resubmitting request every 2 minutes though shows 1 request in network tab (ie11 , chrome both have doing this)

2). has heard of issue akamai before?

i don't know if got right post understand edge server going on timeout request , attempting re-send every couple of minutes, in fact in metadata configuration default http-read should 120 seconds, should ask support check on , maybe make configuration change support particular need lengthy timeout on url.. hope helps!
