duplicate requests, up to 60!

we have this problem, I am new to azure, and from what I can see it is happening, this sounds very bad.

we have a simple aspx page that is requested by the client, on the code behind the request gets authenticated and then it inserts one row per call, instead we see duplicates up to 60x...

anybody can comment on this? searching the net I could find similar problems reported but most of them as WFC calls; in our case it is a http get to an aspx page

testing the client is shows no problems whatsoever. the problem is somewhere on the front end or backend. but as I said, front end and backend are very simple; done this kind of apps so many times I am pretty sure is nothing wrong with the code. we ran also tests, which confirmed the client is making only one http get call. yet on the DB we end up with as many as 60 duplicate entires sometimes (the duplicates are random from 2 to 60)

any help would be appreciated; we know we can go around this by filtering out the duplicated, however if there is a much better solution (and I believe it is) we wuold like to implement that one, maybe it is a known issue and we have to configure our azure services differently?... anything that would help please let us know

thank you

Hi,

 Assuming you have multiple instances running, the load balancer might be thinking that the first request didnt get picked up and retrying another instance, but this does not explain 60 odd requests.
 another reason could be the TCP connection established between the client(browser) and IIS got broken and then the client re-established a connection which ended up on the second server, since you have ruled out any Client side issues.
 At this time I think the best option for you to troubleshoot this issue is to create a Support Ticket and have a support professional look into this issue from IIS and Azure backed perspective, and access to your Subcription details and Deployment information is required.
 You can create a Support ticket at the below link as well as by logging into your azure management portal:
